Gaelic Storm is an American Celtic band founded in Santa Monica, California, in 1996.

In 1996, Patrick Murphy and Steve Wehmeyer joined with Steve Twigger, drummer Shep Lonsdale, fiddler Samantha Hunt, and Uillean piper Brian Walsh to perform at O'Brien's Irish Pub and Restaurant in Santa Monica, California, of which Murphy was the manager.

Their sound engineer at the time, Tom Brown, was also a bagpiper and whistle player and began playing at periods in their show.

Deborah Clark Colon was the fiddler on the three new tracks, "Courting in the Kitchen," "Schooner Lake Set", and "Nancy Whiskey."

For a brief time in approximately 2003, the band recruited their, to date, only male fiddler, Bob Banerjee.

In early 2006, founding member Steve Wehmeyer retired full time from the band and became a college professor.

As of June 2022[update], original members Murphy and Twigger are still in the band, joined by Ryan Lacey (since 2003), Pete Purvis (since 2005) of Merrickville, Ontario, and Natalya Kay (since 2022).

Gaelic Storm also announced in March, that lead guitarist Steve Twigger will not be attending the tour due to health concerns that have led to his absence from the band.
