Saint Agatha's Tower (Maltese: Torri ta' Sant'Agata), also known as the Red Tower (Maltese: Torri l-Aħmar), Mellieħa Tower (Maltese: Torri tal-Mellieħa) or Fort Saint Agatha (Maltese: Forti Sant'Agata), is a large bastioned watchtower in Mellieħa, Malta. It was built between 1647 and 1649, as the sixth of the Lascaris towers. The tower's design is completely different from the rest of the Lascaris towers, but it is similar to the earlier Wignacourt towers. St. Agatha's Tower was the last large-bastioned tower to be built in Malta.
