The Thomas Jefferson National Accelerator Facility (TJNAF), or JLab for short, is a US Department of Energy National Laboratory located in Newport News, Virginia.

Since June 1, 2026 the facility has been operated by SURATech, LLC. The SURATech, LLC team is composed of two team member entities – Southeastern Universities Research Association, Inc. and Virginia Polytechnic Institute and State University, and four major subcontractors – Honeywell International, Inc., Longenecker and Associates, Inc., Akima Support Operations, and AtkinsRéalis.

Until 1996 TJNAF was known as the Continuous Electron Beam Accelerator Facility (CEBAF); commonly, this name is still used for the main accelerator.
