2020 Northern Diamonds season

The 2020 season was Northern Diamonds' first season, in which they competed in the 50 over Rachael Heyhoe Flint Trophy following reforms to the structure of women's domestic cricket in England. The side topped the North Group of the competition, winning 5 of their 6 games, progressing to the final. However, they lost to Southern Vipers in the final by 38 runs.

After the ending of the Women's Cricket Super League in 2019, the ECB announced the beginning of a new "women's elite domestic structure". Eight teams were included in this new structure, with Northern Diamonds being one of the new teams, replacing Yorkshire Diamonds and representing the North East and Yorkshire. Due to the impact of the COVID-19 pandemic, only the Rachael Heyhoe Flint Trophy was able to take place. Northern Diamonds were captained by Hollie Armitage and coached by Danielle Hazell. They played two home matches at Headingley Cricket Ground and one at the Riverside Ground.
