Eva-Maria Houben (born 15 January 1955) is a German composer, organist, pianist, musicologist and university lecturer.

She is a part of the Wandelweiser Group, whose music is characterized by sparse, quiet, fragile soundscapes incorporating frequent silences. According to Radu Malfatti, Wandelweiser music is about "the evaluation and integration of silence(s) rather than an ongoing carpet of never-ending sounds." Michael Pisaro suggests that Wandelweiser works, which often involve extended durations of hours or longer, offer an alternative relationship to time; these pieces "become not a duration to mark, but a space to occupy".
