Boris Roolaid (born Rosenberg, 3 February 1917 – c. 1942) was an Estonian backstroke swimmer. He competed in the 100 m event at the 1936 Summer Olympics, alongside his younger brother Egon, but failed to reach the final. Roolaid took up swimming in 1932, and between 1935 and 1937 won three national titles. In 1941 both brothers were sent to Soviet labor camps, where they died in 1942–43.{{cite Sports-Reference |url=https://www.sports-reference.com/olympics/friv/lists.cgi?id=65 |archive-url=https://web.archive.org/web/20200417055433/https://www.sports-reference.com/olympics/friv/lists.cgi?id=65 |url-status=dead |archive-date=17 April 2020 |title=Olympians Who Were Killed or Missing in Action or Died as a Result of War |access-date=24 July 2018}}
