National School Sport Week was created by the children's charity, the Youth Sport Trust. It began in 2008, and has run every year since. In 2020, the event became National School Sport Week at Home - encouraging children and their families to take part and be active while under lockdown restrictions.

The week-long celebration will champion the return of youth sport and its power to bring people back together. This is done through sports days being held up and down the UK. In 2021, the theme was 'Together Again', and in 2023, the theme will be 'Belonging – a place in sport for every child'. The Youth Sport Trust are urging schools and families to get involved by holding sporting events throughout the week that showcase how inclusive sport can be.
