Brensbach is a municipality in the Odenwaldkreis (district) in Hesse, Germany.

Brensbach lies in the northern Odenwald in the Gersprenz valley.

The municipal election held on 26 March 2006 yielded the following results: The community’s arms bear three charges on a white (silver) background: in the foot of the escutcheon are some blue waves, above which is a red fire, over which is an arc of five six-pointed stars.

According to legend, the namesake brook, when seen under starlight, looked as though it might be burning.

Likelier, though, it looked so at sunset rather than at night, since stars would not be bright enough to produce such an effect.
