Joseph Harp Correctional Center (JHCC) is an Oklahoma Department of Corrections state prison for male inmates located in Lexington, Cleveland County, Oklahoma.

Regarded by his colleagues as an innovative leader and professional in the field of corrections, he recognized that a high school education was one of the greatest needs that many inmates had lacked which could prevent them from gaining legal employment and often times led to a life of crime.

[clarification needed] Under Harp's leadership, Oklahoma State Reformatory was one of the first correctional institutions to establish a fully-accredited high school inside prison walls.

Inmates typically work in the Oklahoma Correctional Industries program, manufacturing furniture or performing data entry to convert old paper records to digital documents.
