Robert Miller Easton (8 June 1898 – 26 May 1987) was a British bass of the mid-twentieth century. He was known both in the concert hall, where he sang in oratorios and other choral works, and in opera, appearing in bass roles at the Royal Opera House, Covent Garden and on tour.
In concert and on record Easton performed many popular ballads, and was one of the original sixteen soloists in Ralph Vaughan Williams's Serenade to Music, premiered and recorded in 1938. In his later years he was a respected and sought-after adjudicator for singing competitions.
