Edna Ngeringwony Kiplagat (born 15 September 1979) is a Kenyan long-distance runner. She is the 2011 and 2013 IAAF World Champion in the marathon. She established herself as an elite marathon runner with wins at the Los Angeles and New York City Marathons in 2010. Her personal best for the distance is 2:19:50 hours, set at the London Marathon in 2012. At age 37, Kiplagat won the 2017 Boston Marathon in a time of 2:21:52 hours.
She finished thirteenth in the long race at the 2006 World Cross Country Championships. In the same season she recorded personal bests in the 5000 metres, with 15:57.3 minutes in July in Nairobi, and the half marathon, with 1:09:32 hours in October in San Jose. In June 2007 she ran the 10,000 metres in 33:27.0 minutes in Nairobi. She won the 2006 Virginia Beach Rock 'n' Roll Half Marathon, the 2007 Lilac Bloomsday Run and the 2007 Bay to Breakers (San Francisco).
Kiplagat finished second behind Emily Chebet at the 2010 Freihofer's Run for Women, running a time of 15:20 and winning $5000 in the process. She managed third place at the Beach to Beacon race in August 2010, and completed the same feat at the Falmouth Road Race two weeks later (finishing behind Lineth Chepkurui and Wude Ayalew at both competitions).
Kiplagat won the Los Angeles Marathon in 2010, only her second marathon ever, and went on to win the 2010 New York City Marathon. She defeated two marathon debutantes, Shalane Flanagan of the United States and Mary Keitany of Kenya, who took second and third, respectively.
She ran a career best of 1:09:00 at the New York City Half Marathon, finishing as runner-up behind Caroline Rotich. She took on Keitany again at the 2011 London Marathon, but was outrun by her domestic rival. Still, Kiplagat was pleased with her third-place performance as her time of 2:20:46 marked a significant personal best, improving upon her previous time by almost five minutes. Kiplagat was the race favourite for the 2011 World Championships Marathon and delivered on her form, taking the women's title in a time of 2:28:43 hours. Her win did not look assured when she fell over in the last 5 km, but her teammate and eventual third placer Sharon Cherop stopped mid-race to help Kiplagat to her feet. Kiplagat, Cherop and Priscah Jeptoo made it a medal sweep for Kenya – the first time that any nation had taken all three medals at a global marathon championship. She entered the Montferland Run with a slight injury and finished as runner-up to Abebech Afework.
She began 2012 on grass and came third at the Kenyan Cross Country Championships. This was her preparation for the 2012 London Marathon, where she was the last runner to challenge eventual winner Mary Keitany and ended the race as runner-up in a personal best of 2:19:50 hours. Kiplagat was selected for the Kenyan Olympic team as a result. She was a comfortable winner of the New York Mini 10K in June. At the 2012 London Olympics she failed to repeat her success in the British capital and managed only twentieth place in the Olympic marathon with a time of 2:27:52 hours. Six weeks later she ran at the Great North Run and had a better performance, setting a personal best of 1:07:41 hours while finishing runner-up to Tirunesh Dibaba.
Later in 2013 she became the first woman to retain the marathon world title when she earned the first gold medal on the opening day of the World Athletics Championships, taking victory ahead of Valeria Straneo and Kayoko Fukushi in a time of 2:25:44 hours.
After finishing on the podium in each of the previous three editions, Kiplagat finally claimed victory at the London Marathon ahead of (unrelated) compatriot Florence Kiplagat in a time of 2:20:21 hours.
2016 saw Kiplagat return to the Top 3 of major races with significantly faster finishing times than just one year prior. She finished in 2:22:36 hours for 3rd place at the 2016 Tokyo Marathon, and in 2:23:28 hours for 2nd place at the 2016 Chicago Marathon.
This victory was her debut Boston Marathon after over a decade of exceptional running. "I have done almost everything in our sport, but it was one of my dreams to run Boston, the world's oldest marathon," says Kiplagat. "And it will also mean I have run five of the six Abbott World Marathon Majors in addition to both the Olympic Games and World Championships." 
In August Kiplagat participated in the 2017 World Championships in Athletics held in London. She won the silver medal in the Women's marathon, in a time of 2:27:18. She was preceded by Rose Chelimo.

Kiplagat is a police woman in Iten, Kenya. "I am one of the role models in my town and country," says Kiplagat. "I have mentored girls in school and I have empowered women to form community associations. I also support less fortunate kids to pay their school fees." 
Kiplagat and her husband have five children – two of her own, two adopted from her sister who died of breast cancer in 2003, and one adopted from a neighbor who died in childbirth in 2013. Her children Wendy, 9, and Carlos, 13, were at the finish line and award ceremony for her victory in the 121st annual Boston Marathon.
