The Hampshire County Darts Organisation (HCDO) is the governing body for darts in Hampshire, England, overseeing competitions, player development, and representing the county at a national level in British Darts Organisation (BDO) and UK darts events.

The HCDO has been a significant part of the English darts scene for decades, participating in county leagues and producing competitive players who go on to compete in national tournaments.

In general, county darts organizations in the UK started to form in the mid-20th century, as darts grew in popularity and more structured competition frameworks were established. The BDO, founded in 1973, helped provide a platform for county-level organizations like HCDO to flourish.

Over the years, Hampshire has fielded competitive teams and hosted numerous local leagues and tournaments. The organization serves as a community hub for darts in the region, promoting the sport at both amateur and professional levels.
