Nelfinavir, sold under the brand name Viracept, is an antiretroviral medication used in the treatment of HIV/AIDS. Nelfinavir belongs to the class of drugs known as protease inhibitors (PIs) and like other PIs is almost always used in combination with other antiretroviral drugs.

Nelfinavir is an orally bioavailable human immunodeficiency virus HIV-1 protease inhibitor (K_i = 2 nM) and is widely prescribed in combination with HIV reverse transcriptase inhibitors for the treatment of HIV infection.

It was patented in 1992 and approved for medical use in 1997.
