The United Sabah Alliance (ms|Gabungan Sabah Bersatu; abbreviated: USA) was a political coalition bringing together Sabah-based parties in Malaysia. It was jointly founded by the Sabah Progressive Party (SAPP) and Homeland Solidarity Party (STAR) after the SAPP left the Barisan Nasional coalition. The Love Sabah Party joined the coalition but left in 2017 due to disagreements.[1] Later, the Sabah People's Hope Party (PHRS) and Sabah People's Unity Party (PPRS) joined the coalition.[2] [3] However, after the 2018 general election, PHRS left the coalition.[4] [5]
