Santa Maria delle Grazie Tower (Maltese: Torri ta' Santa Marija tal-Grazzja), also known as Delle Grazie Tower (Maltese: Torri tal-Grazzja), Madonna delle Gratie Tower (Maltese: Torri tal-Madonna tal-Grazzja) or Blata Bajda Tower (Maltese: Torri tal-Blata l-Bajda), was a watchtower in what is now Xgħajra, Malta. It was constructed in 1620, and was the last of six Wignacourt towers to be built. The tower was demolished in the late 19th century by the British military.
