Pam Lychner State Jail is a Texas Department of Criminal Justice state jail for men located in Atascocita, unincorporated northeast Harris County, Texas, United States, east of Humble. It is 20 miles northeast of Downtown Houston. In July 1995, the jail, initially the Atascocita State Jail, opened. After Pam Lychner, a victim's rights activist, died on board TWA Flight 800 with her daughters on July 17, 1996, the TDCJ board unanimously voted to rename the facility to Pam Lychner State Jail.
