Ampicillin, or aminobenzylpenicillin, is a broad spectrum antibiotic and a derivative of penicillin. It is used to treat infections of E. coli, P. mirabilis, enterococci, Shigella, S. typhosa and other Salmonella, nonpenicillinase-producing N. gononhoeae, H. influenzae, staphylococci, and streptococci including streptoc. It is also widely used in molecular biology labs during the over-expression of proteins in bacterial cells that are tolerant of ampicillin. This ensures that only the bacteria of interest grow in the media and produce the protein of interest.

Ampicillin is a penicillin beta-lactam antibiotic used to eliminate susceptible, usually gram-positive, organisms. Like penicillin, ampicillin inhibits the last stage of bacterial cell wall synthesis by binding to specific penicillin-binding proteins in the bacterial cell wall.

Its IUPAC chemical name is (2S,5R,6R)-6-[[(2R)-2-amino-2-phenylacetyl]amino]-3,3-dimethyl-7-oxo-4-thia-1-azabicyclo[3.2.0]heptane-2-carboxylic acid and it has chemical formula C₁₆H₁₉N₃O₄S, giving it a molecular mass of 349.4048 g/mol.
