RMS Strathnaver, later SS Strathnaver, was an ocean liner of the Peninsular and Oriental Steam Navigation Company (P&O).

She was the first of five sister ships in what came to be called the "Strath" class. All previous P&O steamships had black-painted hulls and funnels but Strathnaver and her sisters were painted with white hulls and buff funnels, which earnt them the nickname "The Beautiful White Sisters" or just "The White Sisters". Strathnaver and her sister ships RMS Strathaird and RMS Strathmore were Royal Mail Ships that worked P&O's regular liner route between Tilbury in Essex, England and Brisbane in Queensland, Australia.

Strathnaver remained in service for just over 30 years, being scrapped in 1962.

The Vickers-Armstrong shipyard at Barrow-in-Furness built all five "Strath" class liners.Strathnaver was launched on 5 February 1931, completed in September 1931 and left Tilbury on her maiden voyage on 2 October.

In 1929 P&O had introduced its first large turbo-electric liner, RMS Viceroy of India. The company chose the same propulsion system for Strathnaver and Strathaird, but the "Straths" were slightly larger ships, their turbo-electric equipment was much more powerful and they were about 3 knots (5.6 km/h) faster than Viceroy of India.

Strathnaver and Strathaird were very similar. Each had four water-tube boilers and two auxiliary boilers. The boilers had a combined heating surface of 56,000 square feet (5,203 m2) and supplied steam at 425 lbf/in2 to two turbo generators. These supplied current to two electric motors with a combined rating of 6,315 NHP or 28,000 shp.British Thomson-Houston of Rugby, Warwickshire built the turbo-generators and motors. The motors drove a pair of inward-rotatingscrew propellers.Strathnaver and Strathaird had three funnels but only the middle one served as a smoke stack: the first and third funnels were dummies.
