She is one of the only three Indian women to score more than 3,000 runs in Women's ODI. In 2019, during the series against South Africa, she became the first Indian cricketer to play in 100th international Twenty20 matches.

Under her captainship, the Mumbai Indians made history as the first team to secure multiple Women's Premier League (WPL) titles. She was awarded the Arjuna Award in 2017 by the Ministry of Youth Affairs and Sports.

Kaur was born on 8 March 1989 in Moga, Punjab, to Harmandar Singh Bhullar, a volleyball and basketball player and Satwinder Kaur, a homemaker. Her parents are baptised Sikhs. Her younger sister Hemjeet, is post-graduate in English and works as an assistant professor at Guru Nanak College in Moga. Her father, who now is a clerk at a judicial court, was once an aspiring cricketer. He was the first coach of Harman when she had begun playing the sport. She took to cricket after joining the Gian Jyoti School Academy, 30 kilometres (19 mi) away from her residence in Moga, where she trained under Kamaldeesh Singh Sodhi. Harman used to play with men in the formative days of her career. She moved to Mumbai in 2014 where she began working for the Indian Railways. Harmanpreet was inspired by Virender Sehwag.

She has claimed to have obtained a Bachelor of Arts from Chaudhary Charan Singh University in Meerut, Uttar Pradesh; though an investigation by university officials found no records of her enrollment and the claims to be fabricated. This was during a request for verification by the Punjab Police, after her honorary appointment there as a deputy superintendent of police. Other reports indicate that she actually studied at the Hans Raj Mahila Maha Vidyalaya college (of the Guru Nanak Dev University) in Jalandhar, Punjab.

In March 2009, she made her ODI debut aged 20 in a match against Pakistan women's team played at Bradman Oval during the World Cup. In the match, she bowled 4 overs conceding 10 runs and also caught Armaan Khan off Amita Sharma. In June 2009, she made her Twenty20 International debut in the ICC Women's World Twenty20 against England women's team at County Ground, Taunton, where she scored 8 runs off 7 balls. Her ability to hit the ball a long way was seen when she played quick-fire innings of 33 against England women's in a T20I game played in Mumbai in 2010.

She was named as Indian women's captain for the 2012 Women's Twenty20 Asia Cup final, as captain Mithali Raj and vice-captain Jhulan Goswami were out because of injuries. She made her debut as captain against Pakistan women's as India defended 81 runs thus won Asia Cup.

In March 2013, she was named ODI captain of India women's when Bangladesh women's team toured in India. In the series, Kaur scored her second ODI century in the 2nd ODI. Kaur finished the series 195 runs at average of 97.50 with a century and a fifty along with 2 wickets.
