Patricia Theresa Schemel (born April 24, 1967) played the drums on the album Live Through This by American Alternative Rock band Hole, replacing their previous drummer, Caroline Rue, who left after the recording of Hole's debut album, Pretty On The Inside. On Celebrity Skin, the final Hole album, she worked up the album's material with frontwoman Courtney Love, Eric Erlandson (guitar) and Melissa Auf der Maur (bass), but was replaced by Samantha Maloney for the album's tour. (Inexplicably, Courtney Love chose to use Patty's name and photo on the album.) Hole split up in May, 2002.

Patty also performed on Courtney Love's solo album, America's Sweetheart, for which she took some partial songwriting credits. As well, she has recorded with Phranc, playing drums on the Goofyfoot EP and with Juliette Lewis's punk rock band Juliette and the Licks, for which she played drums on their debut 6 song EP ...Like a Bolt of Lightning before leaving the band before they recorded their second CD You're Speaking My Language. She also toured as the drummer for LA band Imperial Teen which is led by Courtney's friend Roddy Bottom, formerly of the band Faith No More.

Courtney Love has stated that before the arrival of Dave Grohl in Nirvana, Schemel was being considered by Kurt Cobain to be a possible new drummer for the band.

Schemel is openly lesbian, . commenting to Rolling Stone that "It's important. I'm not out there with that fucking pink flag or anything, but it's good for other people who live somewhere else in some small town who feel freaky about being gay to know that there's other people who are and that it's OK."

One of Schemel's girlfriends acted as Courtney Love's personal assistant during Hole's 1994-1995 world tour, while promoting Live Through This.
