Muriel Evelyn Robb (13 May 1878 – 12 February 1907) was an English female tennis player. She is best remembered for her ladies' singles title at the 1902 Wimbledon Championships. She also won the Irish and Scottish singles titles in 1901 and the Welsh singles title in 1899. She attended the Cheltenham Ladies’ College, in Gloucestershire from 1893 to 1897 and was a member of the Jesmond Lawn Tennis Club in Newcastle. From 1899 to 1902, she participated in four Wimbledon Championships and reached at least the quarterfinals on all occasions.

She was diagnosed with Lymphadenoma and battled the disease for two years and four months before she died on 12 February 1907 in Jesmond, Newcastle upon Tyne. The death certificate listed “exhaustion and cardiac failure” as the immediate cause.

This match set a record for the longest women's final. On the first day of play rain stopped play at 4–6, 13–11. It was replayed the next day when Robb won 7–5, 6–1.
