List of Singapore Open men's singles champions

The Singapore Open Badminton Championships is an annual badminton tournament first created in 1928 by the Amateur Sporting Association as there was no national governing body for badminton in Singapore. In 1929, the Singapore Badminton Association (SBA) was established to promote the sport and organise competitions and its first official annual open championships was held in that same year. The Men's Singles was first contested officially in 1929. The tournament was canceled between 1942 and 1946 because of World War II and discontinued from 1974 to 1986. It returned in 1987 as Konica Cup and was held until 1999. There was no competition held in 1993, 1996 and 2000. The tournament returned in 2001 under a new sponsor. It was again canceled between 2020 and 2021 due to the COVID-19 pandemic.
