Andrew James Stockdale (born 20 July 1976) is an Australian musician best known as the singer and guitarist of Wolfmother. Stockdale was educated in Brisbane, Australia, at Ashgrove State School, Wimbeldon Middle School, The Gap State High School and Kelvin Grove State High School, and lived in Ashgrove and Wimbeldon Village, London as a child.

Andrew graduated with a Bachelor of Arts in Photography from RMIT University in 1999 and worked as a photographer before launching Wolfmother.Stockdale's influences are most commonly cited among late-sixties and early-seventies hard rock and heavy metal guitarists.

Vocally compared to a "cross between Robert Plant and Ozzy Osbourne" by Allmusic, his guitar antics and stage persona are commonly traced to Black Sabbath's Tony Iommi and Jimi Hendrix, while his style can often be compared to progressive rockers Pink Floyd.

Stockdale plays Gibson guitars, primarily a 72' SG standard with a Bigsby vibrato tailpiece in vintage sunburst. He has also been seen using a 61 Reissue Gibson SG. Other times he uses a Gibson Dot Studio ES-335, a white Gibson Flying V and an alpine white Gibson EDS-1275 with golden hardware.

For the recording of the Wolfmother album he used a borrowed Gibson ES-355 through a 60's Marshall. When playing live, he uses Orange amplifiers and cabinets, lately seen in an Orange advertisement with an Orange AD30 and Thunderverb 200 and PCC412 cabinets.

Stockdale also states to use a Fender Stratocaster, though he prefers the Gibson guitars. In recent times he has also started using a Hohner Blues Master Harmonica microphone for some vocals.
