The Texas Medical Center (TMC) is a 2.1-square-mile medical district and neighborhood in south-central Houston, Texas, immediately south of the Museum District and west of Texas State Highway 288. Over sixty medical institutions, largely concentrated in a triangular area between Brays Bayou, Rice University, and Hermann Park, are members of the Texas Medical Center Corporation—a non-profit umbrella organization—which constitutes the largest medical complex in the world. It is home to the largest concentration of researchers, physicians and medical professionals in the world. Immediately adjacent to the Medical Center is NRG Park, the sprawling, multi-venue, events campus that is home to the Houston Texans, Houston Livestock Show & Rodeo and much more. This neighborhood is serviced by the METRORail Red Line, a north-south light rail route which connects the district to Downtown Houston and NRG Park.
