Joseph Harp Correctional Center

Joseph Harp Correctional Center (JHCC), a medium-security prison for men, opened in 1978 on the site of a World War II-era U.S. Navy firing range in Lexington, Oklahoma. The prison’s namesake, Joseph Harp, was an Oklahoma State Reformatory warden from 1949 to 1969, where he started the nation's first fully accredited high school education program in a prison.

JHCC is home to ODOC’s male Mental Health Unit, as well as its Youthful Offender Program. The facility has a capacity of more than 1,300 inmates. The staff works with a diverse group of individuals, as they house mental-health, delayed-sentence, and youthful offender inmates. 

The vast majority of inmates housed at Joseph Harp Correctional Center are incarcerated for a violent crime, and more than one in ten are serving a sentence for first-degree murder.

Visiting Hours and Rules

Normal visiting days are Saturdays and Sundays, as well as all state holidays. The number of hours an inmate may visit varies according to their level. State holidays that fall on Monday through Friday are free visiting days.

Inmates who visit for any length of time during a scheduled visit period will be considered to have visited the entire visiting period, regardless of when the visitor arrived.

Visiting Hours
Level 1 - One hour per week starting at 9 a.m. Fridays
Level 2 - Two hours per week, Saturdays and Sundays

Visitor check in starts at 12:30 p.m. Level 2 inmates may have up to four two-hour visits.

Level 3 - Four hours per week starting at 11 a.m. Saturdays and Sundays
Level 4 - Six hours per week starting at 9 a.m. Saturdays and Sundays

On state-recognized holidays, visiting hours are 9 a.m. - 3 p.m.

Check-in begins typically at 8:30 a.m. To enter, visitors must arrive 1 1/2 hours before visitation is over. Visitors who've left visitation during count time (10 a.m. and 2 p.m.) may not re-enter until count clears.

Segregated Housing Unit

Administrative Segregation and Protective Measures Inmates

Administrative Segregation and Protective Measures inmates may have a one-hour, non-contact visit per week with only the inmate’s mother, father, spouse, legal representative or clergy.
