Nantucket Sleighride is the second studio album by American hard rock band Mountain, released in January 1971 by Windfall Records in the US and by Island in the UK.

Owen Coffin, to whom the song is dedicated, was a young seaman on the Nantucket whaler Essex, which was rammed and sunk by a sperm whale in 1820.

The closing section of the song was used as the theme to the long-running British political television show Weekend World (1972–1988).

The song "Tired Angels" was dedicated to Jimi Hendrix, and "Travellin' In The Dark" was for Pappalardi's mother, Elia.

The bonus tracks on the 2004 edition include the Chuck Berry cover "Roll Over Beethoven" and the original song "Crossroader", which were released as the A- and B-sides of a promotional single in 1971.
