Theodorus Wilhelmus (Theo) Koomen (Wervershoof, 20 mei 1929 – Schermerhorn, 5 april 1984) was a Dutch sports journalist. He was one of the first sports journalists to publish on dope in cycling: "25 jaar doping" (1974). He will always be remembered in the Netherlands for his enthousiastic way of commenting on sports on both radio and television and as the great chroniqueur of the 1960ies and early 1970ies speed skating in the Netherlands in his trilogy about Dutch speed skating: 10 Jaar Topschaatsen, Topschaatsen 72 and Topschaatsen 3.
