The Gagasan Sejahtera (English: Ideas of Prosperity, abbrev: GS) was a coalition of opposition Islamist political parties which promote the "ideas of peace" in Malaysia. The informal electoral pact was formed initially on 16 March 2016 by Pan-Malaysian Islamic Party (PAS) and Parti Ikatan Bangsa Malaysia (IKATAN) as a Third Force to face both ruling Barisan Nasional (BN) and the opposition Pakatan Harapan (PH) coalitions in the upcoming 2018 Malaysian general election (GE14). It had announced on 13 August 2016 the pact to be formally called Gagasan Sejahtera. Pan-Malaysian Islamic Front (BERJASA) had later joined the coalition on 23 September 2016. The formation of the alliance brought criticism from both the main coalitions of BN and PH.
