Tibotec was a pharmaceutical company with a focus on research and development of the treatment of infectious diseases such as HIV/AIDS and hepatitis C. The company was founded in 1994 and then acquired by Johnson & Johnson and merged into its Janssen Pharmaceuticals division in 2002.

The name of the company is derived from the tetrahydro-imidazo[4,5,1-jk][1,4]-benzodiazepine-2(1H)-one and -thione (TIBO) compounds discovered at the Rega Institute for Medical Research (Belgium).
