Agberto Conceição Guimarães (born August 18, 1957) is a former Brazilian middle distance runner who competed at the international level in the 1980s. He set a personal best 800 metres time of 1:43.63 min in Koblenz 1984, a performance which made him temporarily the second-fastest South American 800m runner ever. Guimarães first participated in major international championships at the 1980 Moscow Olympics where he placed fourth in 800 metres (see, for example, "Moscow Olympic Book" / Moskovan Olympiakirja, Tapio Pekola et al., eds., Helsinki, Finland: "Runner" / Juoksija magazine, 1980). Guimarães came sixth in the 800 m final at the 1983 World Championships in Athletics in Helsinki. He won two gold medals and two bronze medals at the Pan American Games. Nowadays Guimarães works at the Brazilian Olympic Committee as its Olympic Solidarity Programme general manager.
