The Training Service Medal (Vietnamese: Huấn-Vụ Bội-Tinh) was a military decoration of South Vietnam.

Established in 1964, the medal recognized outstanding service in an assignment at a military school or training center.

Recipients must have shown outstanding professional ability, devotion to duty, and made significant contributions to the training of the South Vietnamese military.

Individuals who served as instructors, but were not assigned to training centers or schools could also be awarded the medal.

The medal could be awarded to organizations, government officials, civilians, as well as foreigners who, through direct or indirect effort, contributed to the training of South Vietnamese military personnel.
