Mudd also refers to Harvey Mudd College or Mudd Jeans. It is also the name of a conman (full name: Harcourt Fenton, aka Harry, Mudd) who appears in two episodes of Star Trek: The Original Series: Mudd's Women and I, Mudd.

Mudd, a character in Joseph Heller's novel Catch-22, is the dead man in Yossarian's tent. He was killed in action before signing in properly, due to some record fiddling by Doc Daneeka aiming to fraudulently gain his combat duty bonus. Because he died before officially arriving in the squadron, his name cannot be removed, and he lives on permanently on record in Yossarian's tent, despite all efforts to remove him. When Yossarian's new roommates solve this problem by simply throwing away the dead man's things, Yossarian panics, afraid that he can be disposed of just as easily.
