Aljub de la Font Santa ("Font Santa's Well", also known as Aljub des banyos or Aljub de Cas Donat) is an historic building, housing a rainwater storage well, in the municipality of Campos, Majorca. It was built in 1671–1673, during the restoration of the adjacent Church of Saint Joan de la Font Santa, by remodelling the bathing room of a house known as Ca's Donat.
It used a double filter system and delivered water to external and internal wash basins, as well as drinking troughs for animals.
It had a capacity of 400,000 litres (88,000 imp gal) and was in use until the late nineteenth century.
