Rapid Ferry is a shuttle ferry service within the State of Penang, Malaysia, connecting the city of George Town on Penang Island and Butterworth on the mainland. This cross-strait transit has been operational since 1894, making it the oldest ferry service in Malaysia. Its fleet of six ferries carries both passengers and automobiles across the Penang Strait daily; each roll-on/roll-off ferry could accommodate cars either on its lower deck or on both decks.
The first cross-strait ferry service between Penang Island and the mainland began in 1894. Originally a passenger-only service, the ferries were later refitted to carry automobiles in 1925. From 1924, the ferries were operated by the Penang Port Commission (formerly Penang Harbour Board), through its subsidiary, Penang Port Sdn Bhd.
In 2017, the Malaysian federal government began transferring the ferry service from Penang Port Sdn Bhd to Prasarana Malaysia, a government-owned entity which manages urban public transportation across Malaysia. Following the handover, the ferry service has been rebranded as Rapid Ferry.
