Gail Elizabeth Emms MBE (born 23 July 1977) is a retired English badminton player who has achieved international success in doubles tournaments. A badminton player since the age of four, Emms was first chosen to represent England in 1995 and regularly played for her country until her retirement from professional sport in 2008.

Her best results were winning gold at the 2006 World Championships in Madrid, 2004 European Championships in Geneva, and a silver medal at the 2004 Olympic Games, partnering Nathan Robertson in the mixed doubles. At the 2002 Commonwealth Games in Manchester she won a bronze medal with Joanne Goode in the women's doubles and won gold as part of the England team in the mixed team event. In the English National Championships she won the mixed doubles three times and the women's doubles twice.

Emms and Nathan Robertson reached the semi-finals of 1994 World Junior Championships held in Kuala Lumpur. In 1998 she graduated with a BSc (Hons) in Sports Science from Kingston University. After graduating Emms became a full-time professional badminton player with the help of national lottery funded grants paid to her by UK Sport. Her father owned a building firm that collapsed in the recession of the late 1980s leading to a sudden decline in the family standard of living. Her mother, Janice Emms (née Barton), played for the unofficial England women's national football team. Her parents divorced while Emms was in her early teens.

Emms competed in badminton at the 2004 Summer Olympics in women's doubles with partner Donna Kellogg. They defeated Koon Wai Chee and Li Wing Mui of Hong Kong in the first round but were defeated by Zhao Tingting and Wei Yili of China in the second round.

She also competed in mixed doubles with Robertson. They had a bye in the first round and defeated Björn Siegemund and Nicol Pitro of Germany in the second. In the quarterfinals, Emms and Robertson beat Chen Qiqiu and Zhao Tingting of China 15–8, 17–15 to advance to the semifinals. There, they beat Jonas Rasmussen and Rikke Olsen of Denmark 15–6, 15–12. In the final, they lost to the Chinese pair Zhang Jun and Gao Ling 1–15, 15–12, 12–15 to finish with the silver medal.

The 2006 Commonwealth Games brought Emms a silver in the team event, a bronze in the women's doubles (with Donna Kellogg) and a gold in the mixed doubles (with Nathan Robertson). An additional gold together with Robertson followed at the 2006 IBF World Championships.

Emms participated in the women's doubles with partner Donna Kellogg only to be knocked out in the first round by the Chinese pair Wei Yili and Zhang Yawen. Emms then went on to win her first match in the mixed doubles with Nathan Robertson against the Chinese world number 2 pair. Emms and Robertson won the first game 21–16 before Gao Ling and her new partner Zheng Bo hit back to win the second 21–16. The British duo found themselves 12–17 down in the decider only to recover to win 21–19. Emms and Robertson lost out on a medal at the quarter final stage against the world number 10 pair and eventual gold medalist Lee Yong-dae and Lee Hyo-jung of South Korea.

Emms retired after the 2008 Olympic Games in Beijing.
