Siniestro Total (meaning literally 'total write-off' as in the insurance term for a vehicle that is beyond repair following a motor accident) is a Galician punk rock group from Vigo, Spain.

It was founded in 1981 during the cultural movement called Movida viguesa by Julián Hernández, Alberto Torrado and Miguel Costas.

After many changes in personnel, current members are Julián Hernández, Javier Soto, Óscar G. Avendaño, Ángel González and Jorge Beltrán.

The fifth and sixth ones, De hoy no pasa (Today is the last time) and Me gusta cómo andas (I like the way you walk), the rock is still softer, becoming power-pop, whereas the lyrics continue being punk in essence.

The seventh, En beneficio de todos (For the general good), they get back to rock, and lyrics evolve and become more complex.
