Wrigley's Pleasure Planet was a planet in or near Federation space, apparently known for its promotion of hedonistic pursuits.

Crewman Darnell compared Nancy Crater to a girl he met on Wrigley's Planet, before being rebuked by Doctor McCoy. Neither realized "Nancy" was the M-113 creature in disguise, they were each seeing separate illusions of a woman's appearance. (TOS: "The Man Trap")
