The Grand Pump Room is a historic building in the Abbey Church Yard, Bath, Somerset, England. It is adjacent to the Roman Baths and is named for water that is pumped into the room from the baths' hot springs. Visitors can drink the water or have other refreshments while there.
It has been designated as a Grade I listed building since 1950. Along with the Lower Assembly Rooms, it formed a complex where social activity was centred, and where visitors to the city gathered.
