Robert Roberts Taylor Blyth (2 June 1900 – 1956) was a Scottish professional footballer in the 1920s.
Blyth was born in Muirkirk Scotland – his father was the Portsmouth player Bob Blyth, who went on to manage Portsmouth from 1901 to 1904 and his cousins included Bill Shankly and Bob Shankly.
He made eight appearances for Portsmouth in the 1921–22 season[1] before joining Southampton in January 1922. He again only made eight appearances for the "Saints", replacing Charlie Brown,[2] before leaving the club for a brief football career in the United States.
In 1924, he signed with the Boston Soccer Club of the American Soccer League, but saw time in only two games.[3]
