John F. Kennedy is widely believed to have had multiple extramarital affairs, but it’s important to stress that much of the “list” is based on later memoirs, investigative journalism, and sometimes unproven claims rather than courtroom-level proof.

Quick Scoop: Key Names Often Mentioned

Historians and biographers most frequently mention the following women as having had affairs or alleged affairs with JFK:

  • Marilyn Monroe – The most famous alleged affair; many historians think they did have a brief relationship, though details and timing are debated.
  • Judith Campbell Exner – Socialite linked both to JFK and Chicago mob boss Sam Giancana; she claimed a multi‑year affair and said she sometimes passed messages between them.
  • Mimi Alford – Former White House intern who wrote a memoir describing an 18‑month sexual relationship with JFK starting when she was 19.
  • Ellen Rometsch – A model originally from East Germany; U.S. officials worried she could pose a security risk because of her background during the Cold War.
  • Various White House staffers – Historians describe “at least four” secretaries or administrative staffers in the White House whom JFK is believed to have slept with, though not all are publicly named.
  • Hollywood actresses and socialites (rumored) – Names that sometimes surface in books and documentaries include actresses like Gene Tierney and others, but evidence ranges from solid to very speculative.

Because this is partly in the realm of political gossip and retrospective reporting, you’ll see different “all the women” lists in documentaries, YouTube videos, and forum threads, and they don’t always agree or meet strict historical standards.

How Solid Is the Evidence?

You can think of the claims in rough tiers:

  • Strongly supported
    • Mimi Alford (first‑person memoir plus corroborating context).
* Judith Campbell Exner (her own account plus mob–Kennedy links documented by historians, though some details are still debated).
  • Widely accepted but still partly debated
    • Marilyn Monroe (many biographers consider an affair likely, but it’s hard to reconstruct precise dates and extent).
* Multiple White House secretaries and staffers, supported by accounts from aides and later biographies, though not always with full names and documentation.
  • More speculative / rumor level
    • Some Hollywood stars and socialites named in tabloid‑style lists or videos; these often rely on second‑ or third‑hand stories rather than primary documentation.

Today’s “Trending Topic” Angle

Modern discussions about “who did JFK have affairs with” often show up in:

  • Long‑form YouTube videos promising to list “every woman” JFK slept with.
  • Forum threads where people trade names, debate what’s proven vs rumor, and argue about privacy and historical legacy.
  • Articles noting how, in the pre‑internet 1960s, the press largely shielded politicians’ private lives—something that would be almost impossible now.

So, the short version is: JFK almost certainly had multiple affairs, but any exhaustive list is part history, part memoir, and part speculation, and it’s best read with that in mind.
