Serbisyong Inklusibo–Alyansang Progresibo

The Serbisyong Inklusibo-Alyansang Progresibo (lit. 'Inclusive Service–Progressive Alliance'; SIAP or the SIAP Party) is a local political party in the Philippines.

History
SIAP is a political organization established in 2002 by a group of businessmen and figures involved in the Bangsamoro peace process. It was originally founded as a local political party for Lanao del Sur and is associated with its governor Mamintal Adiong Sr. who died in 2004. His son Mamintal Jr. would take over SIAP.

The party would expand to the other provinces of Bangsamoro by 2023.

For the 2025 Bangsamoro election, SIAP and the United Bangsamoro Justice Party have entered a deal where UBJP will not field candidates for municipality-level executive positions in Lanao del Sur. It is also expected to take part in the Bangsamoro Parliament election.
