Abstract: Fluid soap dispenser. Comprises a rear body (2) with wall mounting means and means for the removable support and coupling of a container bottle (10) for soap; a pivoting front cover (3), articulated pivotally to the rear body (2), and means for dispensing the soap, actuated when the cover (3) is pushed against the container bottle (10) and the latter against the rear body (2) by pressing the cover against the rear body. The means for the removable support and coupling of the soap container bottle comprise a projection (9) of the inner wall of the rear body (2), adapted to collaborate with a complementary opening (30) with which the soap container bottle (10) is provided.
