Trần Hiếu Ngân (born June 26, 1974 in Tuy Hòa, Phú Yên)[1] is a Vietnamese Taekwondo athlete who competed in the Women's 49-57 kg weight class at the Sydney 2000 Summer Olympics, where she won the silver medal.

Her father was a disciple of Shaolin kung fu and encouraged his children to learn martial arts for health, fitness and self-defense.

When the Sports and Physical Education Center of the town opened its first Taekwondo class in 1987, he sent 13 year old Hiếu Ngân to learn.

In 1990, at the National Championship held in Ho Chi Minh City, Ngân won the Silver Medal in the Poomsae (Forms) event.

This initial success motivated her in the following years, leading to continued achievements: • Silver Medal in the 51 kg category (1991) • Silver Medal in Poomsae (1992) • Gold Medal in the 55 kg category (1995) These successes established Hiếu Ngân as an influential figure in Vietnamese Taekwondo, prompting her to move from Phu Yen to Ho Chi Minh City to continue her training under more experienced Coaches such as Coach Trương Ngọc Để, aiming to compete in international arenas.
