The Special Forces Regiment (SF) (Sinhala: විශේෂ බලකාය Visēsha Balakāya;) is a special forces unit of the Sri Lanka Army. Founded in 1986 as a combat tracker team, it was established as a regiment in 1988, and later expanded into a brigade. The unit specialises in a number of roles including counter-terrorism, direct action and covert reconnaissance. Much like the British Army Special Air Service, much of the information about the SF is highly classified due to the secrecy and sensitivity of its operations.

The Sri Lanka Army is the oldest and largest of the Sri Lanka Armed Forces. The army was officially established as the Ceylon Army in 1949, though the army traces it's roots back in 1881 when Ceylon Light Infantry Volunteers was created; the army was renamed as the 'Sri Lanka Army' when Sri Lanka became a republic in 1972. In 2024, the Army had approximately 150,000 personnel.
