Parley Sports Club dates from the 1940s when local sportsmen returning from the war founded a football and cricket club located on parish council land. As the club grew it developed into one of the most successful Dorset football clubs winning the Dorset Combination League on a regular basis throughout the 1960s. The clubhouse was officially opened by the famous cricket commentator John Arlott on 13 October 1961.

The cricket club progressed throughout the 1970s and 1980s, moving from being a summer sporting outlet for footballers to being a strong Division One presence in the Bournemouth League. In the late 1980s the cricket club joined the Dorset League where it rapidly progressed through the divisions. Amalgamation with Springfield Amateurs C.C. in 1993 gave the club a presence in the Dorset Premier league along with the introduction of several talented players. Further amalgamation with Monty's C.C. in 1996 gave Parley a strong organisational and youth infrastructure.

In 2000 Parley became Dorset champions for the first time, going through the season unbeaten. Following this the club has built its youth structure to the point where the club is able to field a number of very successful teams at every age group. In subsequent years the success of its youth teams has been remarkable. In 2006 its under 15 team won the Portman Under 15 National Club Championship after a memorable sequence of wins. The core of this team have stayed together and, in 2009, justified the club's youth policy by winning the Dorset Premier League championship; the youngest side ever to do so. The club switched to play some teams in the Hampshire League and successfully climbed the league ladder in a decade. This culminated in the winning of the Hampshire League in 2019. 

Over the years several Parley players have been selected to play for Dorset in Minor County cricket.

As the club continues to grow it looks forward to extending its success and proudly notes the achievement of David Payne in progressing from its youth teams to success in the England under-19 team and a full time contract with Gloucestershire CCC. In July 2021 'Sid' was selected for the full England ODI squad for a series on home soil against Pakistan. Also Tom Barber who toured with the England U19s squad and secured a full time professional position firstly with Middlesex CCC and then with Nottinghamshire CCC. May they be the first two of many.
