Northamptonshire Women joined the national women's cricket structure in
2001, playing in the Emerging Counties competition: prior to this, they had only played one-off games, combined with other county sides. They were promoted from the Emerging Counties league in
2002, and after this moved between Division Three of the
Women's County Championship, and the County Challenge Cup, the tier below the Championship. In
2008, Northamptonshire were promoted from Division 5 Midlands, after which they were a consistent Division 4 and Division 3 side. In 2009, they also joined the
Women's Twenty20 Cup for its inaugural season, and consistently competed in the lower tiers of the competition. 2017 was Northamptonshire's most successful year, seeing them promoted in both the
Championship and the
T20 Cup, from Division 3 to Division 2. They lost only one game all season across both competitions, and were promoted in the Championship by beating
Durham in a play-off by 5 wickets. Northamptonshire batter
Alicia Presland was the 7th highest run-scorer across the Twenty20 Cup, with 224 runs. Northamptonshire were relegated in both competitions the following season, 2018, however. In 2019, they bounced back, again topping their division in both competitions. However, due to a restructure of women's cricket, there was no promotion in 2019, with the County Championship being discontinued and the
2021 Women's Twenty20 Cup being regionalised. In 2021, they competed in the East Midlands Group of the Twenty20 Cup, but finished bottom with one victory. In 2022, they finished top of Group 5 of the
2022 Women's Twenty20 Cup, but lost in the final to
Leicestershire. They also joined the
East of England Women's County Championship in 2022, finishing fourth out of seven in their first season. They won their regional group of the
2023 Women's Twenty20 Cup, defeating
Hertfordshire in the final, and finished fourth in the East of England Women's County Championship that same season. In 2024, the side finished 6th in their group in the
Twenty20 Cup and 4th in their group in the new
ECB Women's County One-Day tournament. ==Players==
