Parti Pesaka Bumiputera Bersatu (PBB; English: United Bumiputera Heritage Party) is a right-wing political party in Malaysia. It is currently the largest political party in Sarawak. Parti Pesaka Bumiputera Bersatu was formed from the combination of three parties in Sarawak; Parti Negara Sarawak, Barisan Rakyat Jati Sarawak and Parti Pesaka Anak Sarawak. The formation of the party was for the purpose of the improvement of the livelihood and protect the rights of the Bumiputera in many fields such as politics, economy and social. Following the fall of BN in the 2018 general election and in the aftermath of a meeting between all Sarawak-based BN coalition parties on 12 June 2018, PBB left the coalition to formed a new Sarawak-based coalition, Sarawak Parties Alliance.
