Scotia was a British passenger liner operated by the Cunard Line that won the Blue Riband in 1863 for the fastest westbound transatlantic voyage. She was the last oceangoing paddle steamer, and as late as 1874 she made Cunard's second fastest voyage. Laid up in 1876, Scotia was converted to a twin-screw cable layer in 1879. She served in her new role for twenty-five years until she was wrecked off of Guam in March 1904.
