The State Intelligence Service (SIS) is an intelligence agency of the Sri Lankan government. It is the primary civilian intelligence agency of Sri Lanka and is responsible for both internal and external intelligence-gathering. It comes under the purview of the Ministry of Defence. The agency was originally named National Intelligence Bureau.

 * 2) Conducting undercover investigations.

Organisation
The SIS is part of the Ministry of Defence and is separate from the Police and Military intelligence but its staff consists of those from both police and military backgrounds. The SIS is led by a director general, traditionally from the Police but this was broken in 2019. .

History
Until 1984, the Sri Lanka Police were responsible for internal intelligence functions, first under the Special Branch, and later under the Intelligence Services Division. The perceived failure of the Intelligence Services Division during the riots of July 1983 led the J.R. Jayawardene Government to re-evaluate the nation's intelligence network, and in 1984 the President set up a National Intelligence Bureau. The new organization combined intelligence units from the Army, Navy, Air Force and Police. It was renamed the State Intelligence Service in 2006.

LTTE agents successfully infiltrated Sri Lankan government and military organizations resulting in the assassinations of several high-ranking military personnel, including Major Tuan Mutalif and Colonel Tuan Meedin both of the Directorate of Military Intelligence, putting Sri Lankan intelligence services in a desperate condition. Under the Defence Secretary Gotabhaya Rajapaksa the intelligence agencies that were in desperate condition built-up a cohesive apparatus, which achieved significant success, including anti-LTTE operations overseas and the SIS played huge role in the Fourth Ealam war. The SIS was involved in the dismantling of the large number of long-term sleeper cells planted by the LTTE in cities helping Police track down criminals who were helping the LTTE for financial gain.

In January 2015 the director of the SIS, Chandra Wakista, resigned following the presidential election, amid allegations of phone tapping of opposition politicians. In March Nilantha Jayawardena was appointed as the SIS director.

In December 2019 the newly elected president Gotabaya Rajapaksa appointed Brigadier Suresh Sallay the former head of Directorate of Military Intelligence as the head of SIS. Sallay is the first director of the SIS to come from the Military Intelligence instead of the Police.
