Jon Hamm’s birth date and core career facts are well documented, but the claims about his Instagram, his Landman exit, and his family are not. Hamm was born March 10, 1971, in St. Louis, Missouri, according to Britannica (reference encyclopedia), and that date anchors every age calculation below.
Full name: Jonathan Daniel Hamm · Born: March 10, 1971 · Known for: Don Draper in Mad Men · Hometown: St. Louis, Missouri
Quick snapshot
- Full name Jonathan Daniel Hamm; born March 10, 1971, in St. Louis, Missouri, per Britannica (reference encyclopedia) (Geneastar (family-history site))
- Best known for playing Don Draper in Mad Men, according to Geneastar (family-history site)
- No source gives a reason for leaving Landman; IMDb (film and TV database) lists the series as Completed without an exit reason
- Instagram: BiographyHive (biography site) lists @jonhamm, while CelebsWiki (celebrity profile site) says he has no official accounts
- Mercury News (news outlet) reported in August 2026 that a first child was expected (Mercury News)
- Birth of that child is not confirmed in the supplied material (Mercury News)
- Hamm told Andy Cohen’s SiriusXM show on September 24, 2026, that he would basically take the year off after the birth (PopCulture (celebrity news site))
- Official Hoppers cast listing still needs to be checked against each voice credit (PopCulture (celebrity news site))
The implication: Only the birth date, the Mad Men role, and the full name have named sources clear enough to repeat without a caveat. The child, the Instagram status, and the voice credits still need checking.
The core profile below has seven rows. The biographical rows are settled, while the spouse and voice rows carry the open questions.

How old is Jon Hamm today?
Date of birth
- Hamm was born March 10, 1971, in St. Louis, Missouri, so the birth date anchors every age calculation in this article.
Age calculation for 2026
- He is 55 in 2026 and turns 56 on March 10, 2027, according to CelebrityBorns (celebrity biography site).
- The age follows directly from the 1971 birth year, so any other figure in circulation needs a dated source.
What this means: The age is simple arithmetic from a documented birth date, which makes it one of the few details here that readers can repeat without hedging.
Who did Jon Hamm voice in Shrek and Hoppers?
Shrek Forever After (2010)
- Brogan, an ogre leader in Shrek Forever After (2010), according to Cast Away App (actor filmography site). The official credit has not been checked.
Who is the voice actor for Mayor Jerry Generazzo in the movie Hoppers?
- Mayor Jerry Generazzo in Pixar’s Hoppers, per Wikipedia (encyclopedia, filmography page). The official cast listing has not been checked.
- Pixar’s Hoppers passed half a billion dollars worldwide, according to Martin CID (talent profile).
Other Hoppers roles in the queries
- Heidi Klum, Meryl Streep, Mabel, The Shark, The Lizard, the owl, and the caterpillar: the supplied material names no voice actor for these roles, so this article states no credit for any of them.
The Hoppers role rests on a single filmography entry, so repeating Mayor Jerry as a confirmed credit would outrun the evidence until the official cast listing is checked.
The trade-off: Brogan appears in listings that point the same way, while the Hoppers credit has only one encyclopedia-style source behind it.
Why did Jon Hamm leave Landman?
What sources confirm his departure
- Hamm played Monty Miller in 10 episodes of Paramount+’s Landman, from 2024 to 2025, according to Wikipedia (encyclopedia, filmography page).
- IMDb lists Hamm’s Landman status as Completed, per IMDb (film and TV database).
What remains unexplained
- No supplied source gives a reason for Hamm leaving Landman, and none announces a departure.
- The Completed status describes the series run, not an exit by Hamm.

Why this matters: The exit question assumes a fact the sources do not state, so any reason offered online is speculation until a named source supplies one.
Does Jon Hamm have an Instagram?
What the fan page source says
- CelebsWiki (celebrity profile site) states that Hamm has no official social media accounts and has criticized social media. This is a low-confidence claim.
- The query spells the name “John Hamm”; the profile in question refers to Jon Hamm.
What official accounts exist
- BiographyHive (biography site) lists the handle @jonhamm in a 2026 biography, a claim that conflicts with the CelebsWiki profile.
- No official account was verified in the supplied material.
The two low-confidence profiles disagree, so printing either a handle or a “no accounts” line as settled fact would repeat an unresolved claim.
The implication: Readers looking for an official feed should check Hamm’s own verified profiles before following any handle listed in a biography.
Who is Jon Hamm’s wife and family?
Spouse
- Hamm married Anna Osceola on June 24, 2023, in Big Sur, California, according to CelebrityBorns (celebrity biography site).
- Hamm met Osceola on the set of Mad Men, according to Yahoo Entertainment (news portal).
- His relationship with Jennifer Westfeldt ran from 1997 to 2015, per Geneastar (family-history site).
Children
- Mercury News (news outlet) reported that the couple was expecting a first child, with the news breaking in August 2026.
- Hamm said on Andy Cohen’s SiriusXM show that he would basically take the year off after the birth, per PopCulture (celebrity news site).
- IMDb (film and TV database) lists no children as of its most recent data, so a birth remains unconfirmed.
An expected child is a reported plan, not a confirmed birth, so a reader who writes that Hamm has a child would publish a claim the sources do not yet support.
What this means: The family answer is partly confirmed, with a marriage and a pregnancy announcement, and partly open, with the birth status still missing. Those two halves need to stay separate.
Key dates on record
- June 24, 2023: Hamm married Anna Osceola in Big Sur, California, according to CelebrityBorns (celebrity biography site).
- February 15, 2024: Variety reported that Hamm joined Taylor Sheridan’s Landman, per Wikipedia (encyclopedia, filmography page).
- April 2025: Apple TV’s Your Friends & Neighbors premiered with Hamm as Andrew “Coop” Cooper, per AARP (membership magazine).
- September 24, 2026: Hamm said he would take the year off after the birth, per PopCulture (celebrity news site).

The pattern: Career dates trace to reference and industry pages, while family dates rest mostly on celebrity and news profiles, so they carry more risk.
Confirmed facts and open questions
Confirmed facts
- Full name Jonathan Daniel Hamm; born March 10, 1971, in St. Louis, Missouri, per Britannica (reference encyclopedia)
- Best known for Don Draper in Mad Men, according to Geneastar (family-history site)
- Brogan, the voice role in Shrek Forever After, per Cast Away App (actor filmography site); the official credit is still unchecked
What’s unclear
- Why Hamm left Landman: no supplied source gives a reason
- Instagram: one profile lists a handle, another says he has no accounts
- Hoppers credits: the Mayor Jerry role has not been checked against the official cast listing
- Other Hoppers roles named in the queries: no credit in the supplied material
- Children: a birth is expected but not confirmed
- Net worth and height: no sourced figures
- Vitiligo and Harry Potter claims: no sourced support
The pattern: Three claims carry a named source, while seven stay open until a Tier 1 or Tier 2 source settles them.
What Hamm has said about fatherhood and aging
I will be the old dad, but so it goes. It could be a good thing. We’ll see.
Jon Hamm, via Mercury News (news outlet)
Hamm said he is very excited to start a family, because he has been around kids his whole life, according to Economic Times (news outlet).
On aging, Hamm has said that it is fun and that he has earned it, per AARP (membership magazine).
Every quote and paraphrase here comes from Hamm himself. The supplied material did not verify a second named speaker, so no other voice is quoted.
Hamm’s biography is the solid part of this record, and the questions people type most often are the ones the sources leave open. Editors repeating these claims must either attach a named, verified source to each detail or cut the Landman exit reason and the Instagram handle from the story.
