Sarah de Oliveira Nikitin (born December 27, 1988) is a Brazilian competitive archer. A member of Brazil's archery squad in three editions of the Pan American Games (2007, 2011, and 2015), and at the 2016 Summer Olympics, Nikitin scored her only career medal with a bronze over Venezuela's Leidys Brito in the women's individual recurve tournament at the 2014 South American Games in Santiago, Chile. Nikitin currently trains under the tutelage of head coach Evandro Azevedo for the Brazilian national squad, while shooting at a local archery range in her native São Paulo.
Nikitin was selected by the Brazilian Olympic Committee to compete for the host nation's archery squad at the 2016 Summer Olympics in Rio de Janeiro, shooting in both individual and team recurve tournaments. First, Nikitin discharged 609 points, 8 perfect tens, and 3 bull's eyes to take the fiftieth seed heading to the knockout draw from the classification round, along with the trio's cumulative score of 1,845. Sitting at eleventh in the team recurve, Nikitin and her compatriots Ane Marcelle dos Santos and Marina Canetta put up a gallant fight amid the loud applause of their parochial crowd, but bowed out of the opening round match to the Italians in straight sets 0–6. In the women's individual recurve, Nikitin was unable to overthrow North Korea's Kang Un-ju early in the opening round match that abruptly ended her Olympic debut in a severe 0–6 defeat.
