Clubul Sportiv Orășenesc Plopeni, commonly known as CSO Plopeni, or simply as Plopeni, is a Romanian amateur football club based in Plopeni, Prahova County. The club was originally established in 1947 under the name of Metalul Plopeni.

Metalul merged with Rapid Mizil in 1967, was enrolled directly in the third tier and was for decades a constant presence at the level of Liga II and Liga III. In 2004 the club was dissolved due to financial difficulties and re-established only in 2006, after two years of inactivity, this time under the name of Intersport Plopeni.

Despite its good financial conditions for the fourth level, Intersport failed to promote in the next three years, then in 2009 the football club was included as a section of the multi-sport entity CSO Plopeni. Intersport was renamed as CSO Plopeni and promoted back to Liga III after only one year. In the third season after promotion, CSO Plopeni withdrew due to financial problems and enrolled in the Liga IV, where is currently playing.
