The 64th (Northumbrian) Heavy Anti-Aircraft Regiment, Royal Artillery, was an air defence unit of Britain's Territorial Army (TA) formed on Tyneside during the 1930s. After defending the UK during the Battle of Britain and the Blitz early in World War II, it went on to see service in North Africa, Italy, Yugoslavia and Germany. It continued in the postwar TA until it was amalgamated in 1954.
