Rangkaian Ketiga (Network Three) was a Malaysian television station for Sabah and Sarawak, operating out of Kota Kinabalu. It started in 1970 as a television station owned by the government of Sabah, before being acquired by Radio Televisyen Malaysia in 1975. The introduction of RTM2 in the two states led to its dissolution in 1985.
