MV Orpheus was a cruise ship launched on 25 March 1947 and completed on 17 January 1948 by the shipyard Harland & Wolff in Belfast as Munster for B&I Line.

[1] It replaced the earlier Munster, built in 1938, which sank in 1940.

Epirotiki overhauled the ship for two years to bring it in line with market conditions, reducing its capacity for passengers from 1,500 to 372 while increasing passenger comfort, adding a pool and redesigning the cabins.

Orpheus was relocated to the Americas where it sailed in Alaska, Mexico, and Panama for about one year.

In 1974, the cruise line Swan Hellenic chartered the ship.
