The Pan-Borneo Highway, also known as the Trans-Borneo Highway or the Trans-Kalimantan Highway, is a road network on Borneo Island connecting two Malaysian states, Sabah and Sarawak, with Brunei and the Kalimantan region in Indonesia. The highway is numbered AH150 in the Asian Highway Network and as Federal Route 1 in Sarawak. In Sabah, the route numbers given are 1, 13 and 22. The highway is a joint project between both governments which started as soon as the formation of Malaysia in 1963 which comprised Malaya, Sabah, Sarawak and Singapore. The lack of a road network system in Sarawak was the main factor of the construction.

The Sarawak section of the Federal Route 1, Asian Highway Route AH 150, also known as Pan Borneo Highway Sarawak or Sarawak First Trunk Road, is a 1077-km federal highway in Sarawak, Malaysia, making the highway as the longest component of the Malaysian portion of the larger Pan Borneo Highway network. Construction of the highway began in 1965 after Sarawak became a member of the federation of Malaysia in 1963.
