At that stork delivery,
Mommy screamed:
"Woe is me!
Such a dork.
Hey, Mr. Stork,
Behold my misery!
Pete is ghastly,
Pete's a blob,
Pete's a nasty naughty slob!"
―Pete singing about being delivered to his mother[src]

Maw Pete, often simply referred to as Maw or Mommy, is Pete's mother, who was first mentioned in Donald Duck Finds Pirate Gold, a 1942 comic by Carl Barks and Jack Hannah. In this story, Pete reveals that his mother is a resident of Pittsburgh, Pennsylvania, USA.

She made her first actual appearance in The River Pirates by Carl Fallberg and Paul Murry, in which she was shown to be just as much of a criminal as her son. However, in her latest comic book appearance, The Spirit of Christmas (Walt Disney's Comics and Stories #663), a flashback of Pete shows that his mother was a very decent and honest woman during Pete's childhood.

In the film Mickey, Donald and Goofy: The Three Musketeers, Pete shows a portrait of his mother, imitating her voice while singing the song "Petey's King of France".

In the Mickey Mouse Clubhouse episode "Mickey's Pirate Adventure", Peg-Leg Pete shows a picture of his mother.
