Siegfried Willem "Wim" Esajas (16 April 1935 – 30 April 2005) was a middle-distance runner from Suriname, who qualified for the Athletics at the Men's 800 m event at the 1960 Summer Olympics in Rome, Italy and was supposed to be the first Surinamese Olympian. Esajas missed the event, and it was alleged that he overslept it, whereas he was simply given a wrong starting time by Fred Glans, the head of Suriname's Olympic delegation.
