The Riordans was a significant Irish television drama serial that aired on RTÉ from January 4, 1965, to May 28, 1979. Created by James Douglas, set in the fictional townland of Leestown in County Kilkenny. It focused on the lives of the Riordan farming family. The show is notable for its pioneering use of location filming, which distinguished it from many contemporaneous dramas that were primarily studio-based. This approach influenced later British series, such as Emmerdale Farm (now Emmerdale).

The Riordans achieved considerable popularity and is remembered for its blend of drama, humour, and social commentary. It tackled controversial topics and provided agricultural advice, making it a staple of Irish television for 15 years. The series is also credited with helping to establish a distinct voice for Irish television drama, paving the way for future productions.

The show featured notable actors, including Gabriel Byrne in one of his early roles.
