The Intratec TEC-DC9 (TEC-9) is a blowback-operated semi-automatic firearm, chambered in 9×19mm Parabellum, and classified by the U.S. Bureau of Alcohol, Tobacco, Firearms and Explosives as a handgun.

Designed by Intratec, an American offshoot of Interdynamic AB, all the three models are referred to as the TEC-9, although only one model was sold under that name.

The TEC-9 is made of inexpensive molded polymers and stamped steel parts. Magazines with 10-, 20-, 32-, 50- and upwards of 72-rounds are made.
