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.

Malaysian Federal Roads System, is the main national road network in Malaysia. All Federal Roads in Malaysia are under the purview of the Ministry of Works (MOW). According to the Ministerial Functions Act 1969, the MOW is responsible to plan, build and maintain all Federal Roads gazetted under the Federal Roads Act 1959. However, most of the Federal roads' projects were built and maintained by the Malaysian Public Works Department (JKR), which is also one of the implementing agencies under the MOW.
