Patrick Allan Torpey (December 13, 1953 – February 7, 2018) was an American musician, best known as the drummer for the rock band Mr. Big, as well as playing for other various singers and artists such as John Parr, Belinda Carlisle, Robert Plant, Montrose, Richie Kotzen and the Knack.

He recounts the beginning of his career: "I'm a pretty good softball player and joined an entertainment league, and through that, I was able to make some new friends and network my way into a couple of gigs.

I became a regular on the American Bandstand and Solid Gold TV shows performing with Ben E. King, Mike + The Mechanics, Melissa Manchester, Bob Geldof, and a few I can't even remember."

In 1985, Torpey successfully auditioned for the British pop-rock singer John Parr, who at the time had a #1 hit song, "St. Elmo's Fire", and had attained the opening slot for Tina Turner on her Private Dancer tour.

Torpey further explains: "In 1987, I was doing a television show with Roger Daltrey and Bobby Colomby from Blood, Sweat and Tears approached me and asked me if I was available to do some studio work.

For fourteen years Mr. Big toured the world, headlining as well as opening for Aerosmith, Rush, Bryan Adams, the Scorpions and others, garnering a reputation for their musicianship and live performances.

Torpey played for the reformed version of Montrose; the "new" band stepped up for a memorable debut performance at the Los Angeles Key Club on April 29, 2002, in honour of Ozzy Osbourne and Mötley Crüe drummer Randy Castillo.

At the end of 2006, Torpey joined "The Exile Social Club", a band that relives old rock 'n' roll hits and includes Chuck Wright from Quiet Riot, Jason Hook, and David Victor.

He announced on July 25, 2014, that he had been diagnosed with Parkinson's disease and would be unable to perform all of his normal drumming duties on the band's 2014–15 world tour in support of the album ...The Stories We Could Tell.
