At the 2016 Rio de Janeiro Olympics, Felix bumped her overall Olympic haul to nine overall medals: six golds and three silvers, tying Jamaican legend Merlene Ottey's record for the most Olympic medals won by a female track and field athlete, although most of Ottey's medal collection consists of individual medals. Felix's hope of winning the 400 meters Olympic gold medal came up short after she lost by 0.07 to Shaunae Miller of the Bahamas, who made a legal but controversial dive across the finish line as Felix was quickly closing the distance. Felix recovered from the disappointing performance to win two golds with the U.S. 4 × 100 meters and 4 × 400 meters relay teams. The 4 × 100 meters relay win drew much controversy, as Team USA was initially disqualified in their semi-final run after Felix had dropped the baton during the handoff attempt to English Gardner. However, replays showed that the Brazilian sprinter in the neighboring lane swung her arm and accidentally impeded Felix right before the handoff, causing her to lose her balance. After the appeal was accepted, Team USA was awarded a solo run the following day. With a successful time trial, Felix and her teammates advanced to the final, in which they won in 41.01 seconds, the second-fastest 4 × 100 meters relay time in history.
