Hay Wharf or Haywharf (Maltese: Xatt it-Tiben) is a naval base in Marsamxett Harbour, in Floriana, Malta.

The wharf has been the main base of the Maritime Squadron of the Armed Forces of Malta since 1977,[1] and a new facility was built between 2015 and 2016.

[3] It has also been proposed that the wharf was named after Lord John Hay, who was the Commander in Chief of the Mediterranean Fleet based in Malta between 1883 and 1887.

[5] The 1st (Maritime) Battery of the Armed Forces of Malta moved from Senglea to Hay Wharf in October 1977.

The battery became the Maritime Squadron of the Armed Forces of Malta in 1980, retaining the same base.
