Sunday Bada (22 June 1969 – 12 December 2011) was a Nigerian sprinter who specialized in the 400 metres event.

[1] He broke through at the regional level in 1990, with bronze medals in both 200 and 400 metres at the 1990 African Championships.

[7] Bada made his definite breakthrough in 1993, when he won the silver medal at the World Indoor Championships.

[4] In the 1995 World Championships relay he won a bronze medal together with teammates Udeme Ekpeyong, Kunle Adejuyigbe and Jude Monye.

[11] However, Bada just barely managed to improve this time during the outdoor season, with 45.37 seconds, and would never run a sub-45 race again.

[4] A highlight in these years was the 4 x 400 m relay at the 2000 Olympics, where the Nigerian team won silver medals, later upgraded to gold after the disqualification of the US.
