INTAN Sarawak Regional Campus (INSARA) was formerly known as INTAN Northeast Region (INTILA). INTILA began operating on the 17th Floor of the Federal Secretary's Office, Sultan Iskandar Building, Simpang Tiga Road, Kuching in 1999 before moving to the Temporary Building at No. 37, Badrudin Road, Kuching.

INTILA was established on 27 January 1999 as a result of a Cabinet Meeting decision. It was officially launched in Kuching, Sarawak on 26 March 1999 by His Excellency Tan Sri Abdul Halim bin Ali, Chief Secretary to the Government. INTILA was established as an institute responsible for promoting training programmes and courses aimed at addressing the training needs of federal civil servants in Sarawak as well as those from Sabah and Peninsular Malaysia.

On 26 March 2001, the name INTILA was changed to INTAN Malaysia Sarawak. This was in conjunction with the establishment of the new campus in Sabah known as INTAN Malaysia Sabah based in Kota Kinabalu. This historic move saw the shift of training functions by INTILA being addressed by the new campus in Sabah.

Then, on 9 April 2003, INTAN Malaysia Sarawak was again renamed to INTAN Sarawak Regional Campus or INSARA. Another historic landmark for INSARA was recorded when it moved to its current permanent campus in Kota Samarahan Division on 18 August 2011.

In line with the Government's objective of enhancing human capital capacity and competitiveness of the public services, and thus providing best service delivery to the people, INTAN Kiara (Headquarters) has earmarked each regional campuses based on excellence building capacity.
