HT-7, or Hefei Tokamak-7, is an experimental superconducting tokamak nuclear fusion reactor built in Hefei, China, to investigate the process of developing fusion power. The HT-7 was developed with the assistance of Russia, and was based on the earlier T-7 tokamak reactor. The reactor was built by the Hefei-based Institute of Plasma Physics under the direction of the Chinese Academy of Sciences.

The HT-7 construction was completed in May 1994, with final tests accomplished by December of the same year allowing experiments to proceed.

The HT-7 has been superseded by the Experimental Advanced Superconducting Tokamak (EAST) built in Hefei by the Institute of Plasma Physics as an experimental reactor before ITER is completed.
