525th (Antrim) Coast Regiment, Royal Artillery (TA) was a volunteer coastal defence unit of Britain's Territorial Army from 1937 until 1956. It was the first Territorial Army unit to be raised in Northern Ireland.

The regiment was originally raised as an independent battery - 188th (Antrim) Heavy Battery, Royal Artillery (TA) in 1937. In 1940 the unit was expanded to Regimental status and designated 525th (Antrim) Coast Regiment, Royal Artillery (TA). The Regiment was tasked with the Defence of the Port of Belfast, which in 1939 included four 6-inch Breech Loading guns. Two of these guns were emplaced at Grey Point Fort and another two at Kilroot.

In 1945 at the end of the Second World War the unit was placed in suspended animation. On the re-establishment of the Territorial Army in 1947 the unit was reconstituted as 429th (Antrim) Coast Regiment, Royal Artillery (TA). On the dissolution of coast artillery in 1956 it was converted to Royal Engineers and redesignated as 146th (Antrim Artillery) Field Engineer Regiment, Royal Engineers.
