Those Darn Accordions, commonly abbreviated as TDA, are an American accordion band from San Francisco, California, originally formed in 1989 by Linda "Big Lou" Seekins.

Boasting several accordionists whose numbers have fluctuated over the years and rounded out by a bassist and a drummer, Those Darn Accordions play a multi-genre mix of rock, pop and polka originals, characterized by the unusual use of effects and distortion on their accordions and the humorous lyrics of current frontman Paul Rogers. The band also performs from an extensive repertoire of covers, ranging from traditional accordion standards and polkas to hard rock, funk and new wave songs.
