Paul Marc Rousseau (born March 18, 1989) is a Canadian musician who is the lead guitarist for the rock band Silverstein.

In 2005, Rousseau attended the record release show for Silverstein's second studio album, Discovering the Waterfront, at the Burlington YMCA.

"[3] Over the following years, Hamilton would draw on his knowledge of music, setting tasks for Rousseau such as learning to play the second stanza of Billy Joel's "Movin' Out (Anthony's Song)".

In 2008, while dealing with a bad breakup, Rousseau was invited by a friend who was working for Silverstein on tour to come hang out on their bus to get his mind off of his personal issues.

[5] On September 25, 2012, Silverstein announced on their Facebook that guitarist Neil Boshart was no longer a member of the band, after 11 years.

They also announced Rousseau as Boshart's replacement, noting that as a member of the Silverstein "touring family", he was familiar with the band and its ways.

[7] In January 2014, while on tour with Silverstein in Canada, Rousseau fell ill and was taken to a hospital in Cornwall, Ontario, where he underwent emergency abdominal surgery.

[10] In addition to playing lead guitar on Silverstein's 2017 album, Dead Reflection, Rousseau is credited as a producer.

The Good Boys, a throwback to the days when bands wore collared shirts and neckties on stage, is described by their label as "more Ed Sullivan than MTV".
