Salwa Eid Naser (née Ebelechukwu Agbapuonwu, born 23 May 1998) is a Nigerian-born Bahraini sprinter who specialises in the 400 metre race. She was the 2019 World champion, with the third-fastest time in history of 48.14 seconds, becoming the youngest-ever champion in the event and the first woman representing an Asian nation to win it at a World Championships. The mark places her only behind the contested results of Marita Koch (47.60; 1985) and Jarmila Kratochvílová (47.99; 1983). At 19, Naser was the 2017 World 400 metre silver medallist. As a member of the Bahraini mixed-gender 4 × 400 m relay team, she also won the 2019 World Championships bronze medal.

In the 400 metre sprint, Eid Naser was the 2014 Youth Olympic silver medallist and 2015 World Youth champion. At the 2015 Military World Games, she won her first senior medal, gold. At 18, she skipped the 2016 World U20 Championships, in which the winning time was 51.32 s, to compete with the world's best 400 m sprinters at the 2016 Rio Olympics, where she placed equal ninth in the semi-finals in 50.88 s. She is a multiple medallist of Asian Games, Asian Championships, and other top-level military and pan-regional competitions, both individually and in relays. A two-time 400 m Diamond League champion, as of December 2022, she held the eighth-fastest Asian results of all time, nine marks in the top 10, and 18 in the top 20.
