Daniel "Dan" Topolski (4 June 1945 – 21 February 2015) was a British author, rower, rowing coach and commentator on BBC television.

He coached the Oxford University Boat Club crew on fifteen occasions, leading them to victory twelve times, including a ten-win streak.

The son of the Polish artist Feliks Topolski and actress Marian Everall, Daniel attended the Lycée Français Charles de Gaulle in London, before going to Westminster School and New College, Oxford, where he read geography.

[1] He was taught sculling by his father, on Regent's Park lake in London, and captained Westminster School's boat club for two consecutive years.

[7] Of the fifteen Boat Races in which he was coach, Oxford won twelve including an unbroken run of ten victories between 1976 and 1985.

This run of success and its continuation after Topolski's departure brought Oxford to a point in 1992 where they had won sixteen of the last seventeen races and were within one victory of equalling Cambridge's overall total of wins.

[1] Topolski won the inaugural William Hill Sports Book of the Year in 1989 as the co-author (with Patrick Robinson) of True Blue: The Oxford Boat Race Mutiny.
