Doxycycline is a tetracycline antibiotic that is commonly prescribed by medical doctors for infections and to treat acne. It may also be used to treat urinary tract infections, gum disease, and other bacterial infections such as gonorrhea and chlamydia. Doxycycline is also used commonly as a prophylactic treatment for infection by Bacillus anthracis (anthrax). It is also effective against Yersinia pestis and malaria.

Its chemical name is (4S,4aR,5S,5aR,6R,12aS)-4-(dimethylamino)-1,4,4a,5,5a,6,11,12a-octahydro-3,5,10,12,12a-pentahydroxy-6-methyl-1,11-dioxo-2-naphthacenecarboxamide.

At subantimicrobial doses, doxycycline is an inhibitor of matrix metalloproteinases, and has been used in various experimental systems for this purpose.
