Irina Voronina (Russian: Ирина Воронина, born December 19, 1977 in Dzerzhinsk, Russia) is a Russian model. She was chosen as Playboy's Playmate of the Month in January, 2001 and has appeared in numerous Playboy videos. She has also modelled for another adult magazine, Perfect 10.

She appeared in the 2005 Playmates at Play at the Playboy Mansion swimsuit calendar as calendar girl of May. The calendar was the inaugural Playmates at Play calendar and it was shot on the grounds of Playboy Mansion in 2004. It was Playboy's first attempt at creating a non-nude swimsuit calendar featuring Playmates similar in style with those from Sports Illustrated Swimsuit Issue.

Irina was also featured twice in the Playboy Cyber Club's celebrity photographer section. One was a topless pictorial shot by Las Vegas Mayor Oscar Goodman. Another was presented as if shot by Manne Quinn, the Axe mannequin. After being disrobed and photographed, Irina presumably is overcome by the Axe effect and cannot resist making advances on the dummy.

She has recently appeared in the films Reno 911!: Miami and Epic Movie. She is also a series regular on Adult Swim's first ever live action show Saul of the Mole Men (Cartoon Network), playing the role of Fallopia. Her feature film credits include 2007's Balls of Fury.

She is the 2008 St. Pauli Girl Beer spokesmodel, a position held in previous years by other Playboy Playmates.
