The Cranleigh line was a railway line in England that connected Guildford in Surrey, with Horsham in West Sussex. Construction of the line was started by an independent company, the Horsham and Guildford Direct Railway, but management failures delayed construction, and the company was taken over by the London, Brighton and South Coast Railway (LBSCR). The LBSCR completed the construction of the line and it was opened in 1865; it was nearly 16 miles in length.
