Mares de tempo is an album by Galician gaita (bagpipes) player Susana Seivane, released in 2004.

Seivane's third record, in which some well-known Galician musicians participated, is supplemented by a DVD that contains footage of her on stage and off.

Mares de tempo is a title that has been taken from the work of the Galician poet Celso Emilio Ferreiro: "Longa noite de pedra".

The song, "Muneira de Alen", is one that Seivane had recorded on her previous album, This time it is given a heavier treatment.

Almost all the tracks can be described as folk-rock and for the first time there is no acoustic guitar.
