Leimbach (French pronunciation: [laimbak] ⓘ) is a commune in the Haut-Rhin department in Grand Est in north-eastern France.

Leimbach was historically attested as Leymbach in 1223.

The toponym Leimbach is of Germanic origin, cognate to modern German Lehm, denoting clay.

The Germanic hydronym *-bak(i) entered the French language via High German, and took on two forms: the Germanic form -bach and Romantic -bais.
