David Michael Alexander (June 3, 1947 – February 10, 1975) was an American musician, best known as the original bassist for influential proto-punk band The Stooges.

Although Alexander was a total novice on his instrument, he was a quick learner and subsequently had a hand in arranging, composing and performing all of the songs that appeared on the band's first two albums, The Stooges and Fun House.

[4] After his dismissal, Alexander was replaced by bassists Zeke Zettner and Jimmy Recca, though Ron Asheton played bass on the first studio album post-Alexander, Raw Power.

[6] During The Stooges' induction into the Rock and Roll Hall of Fame in 2010, Iggy Pop paid tribute to Alexander during his speech.

At Watt's first performance with the Stooges at the Coachella Valley Music and Arts Festival in May 2003, he wore a Dave Alexander t-shirt as a tribute.
