J.P. (John Paul) Cormier (born January 23, 1969) is a Canadian bluegrass/folk/Celtic singer-songwriter and multi-instrumentalist. He has won thirteen East Coast Music Awards and one Canadian Folk Music Award. Cormier was born in London, Ontario, and began playing guitar around age five. As a child, he displayed an unusual ability to play various instruments by ear and won a guitar contest at age nine. Appearances on Up Home Tonight, a television show devoted to bluegrass music, followed at age fourteen.

In the mid-nineties, he entered the musical scene of his beloved East Coast and the Island called Cape Breton. He exploded onto the trad music scene there as a fiddler, performing some of the most challenging music ever produced by legends like Winston Fitzgerald and Angus Chisholm with a facility that stunned onlookers. Especially those who knew he wasn't born there but in Ontario to Cape Breton parents. Somehow, some way, his music was the real thing, sounding like he had been steeped continually in a handed-down brew of family tradition from the old country.

In 2020 he released 'Now that the Work is Done', followed by 'Us', in 2021. His latest album is '50 Years of Guitar'.

J.P. has an active YouTube channel where he connects with fans. Every week he posts new episodes of Life In Music, Guitar Stuff With John, and the Wednesday night live broadcast of String Theory, an interactive question-and-answer show. People still leave his shows confused, amazed, and wondering what they just saw. Did they see a storyteller? A Songwriter? Arguably one of the best guitar players in the business today? Someone who crosses the lines between different instruments like there are no lines? Of all the things he is, foremost he is an entertainer.
