D'arcy Elizabeth Wretzky (born May 1, 1968 in South Haven, Michigan), also known simply as D'arcy, is a rock musician best known for her work as a bass player with the alternative rock band The Smashing Pumpkins.

Wretzky and bandmate James Iha dated for a time in the early 1990s, with their breakup adding considerable tension to the recording of Siamese Dream. Wretzky went on to marry Kerry Brown, the drummer of the band Catherine, in 1994. Her vocals were featured on the tracks "Four Leaf Clover" and "Punch Me Out" on the band's 1996 LP, Hot Saki and Bedtime Stories. She also appeared in the video for "Four Leaf Clover". The couple has since been divorced for several years.
She was arrested January 25, 2000 in Chicago after she purchased three bags of crack cocaine. According to police, undercover officers observed Wretzky and a male companion enter a building on West Grand Avenue and then shortly afterwards returned to their car. The driver, identified as Tony Young, then drove off without his headlights on and proceeded to make two illegal U-turns before police stopped the car. When searched, the police found drugs in Young's pocket. The driver insisted they were not his, claiming that Wretzky "handed me some rocks to hold." Upon questioning, she admitted giving him the three plastic bags. She successfully completed a court-ordered drug education program, and the charges were dropped. She has remained almost entirely out of the public eye since 2000.
