Apothecary (/əˈpɒθəkəri/) is an archaic English term for a medical professional who formulates and dispenses materia medica (medicine) to physicians, surgeons and patients. The modern terms pharmacist and, in British English, chemist have taken over this role.

In some languages and regions, terms similar to "apothecary" have survived and denote modern pharmacies or pharmacists.

Apothecaries' investigation of herbal and chemical ingredients was a precursor to the modern sciences of chemistry and pharmacology.

In addition to dispensing herbs and medicine, apothecaries offered general medical advice and a range of services that are now performed by other specialist practitioners, such as surgeons and obstetricians. Apothecary shops sold ingredients and the medicines they prepared wholesale to other medical practitioners, as well as dispensing them to patients. In 17th-century England, they also controlled the trade in tobacco which was imported as a medicine.

The term "apothecary" derives from the Ancient Greek ἀποθήκη (apothḗkē, "a repository, storehouse") via Latin apotheca ("repository, storehouse, warehouse", cf. bodega and boutique), Medieval Latin apothecarius ("storekeeper"), and eventually Old French apotecaire.

In some European and other languages, the term is current and used to designate a pharmacist/chemist, such as Dutch and German Apotheker, Hungarian patikus, Irish poitigéir, Latvian aptiekārs and Luxembourgish Apdikter. Likewise, "pharmacy" translates as apotek in Danish, Norwegian and Swedish, apteekki in Finnish, apoteka in Bosnian, patika in Hungarian, aptieka in Latvian, апотека (apoteka) in Serbian, аптека (apteka) in Russian, Bulgarian, Macedonian and Ukrainian, Apotheke in German and apteka in Polish. The word in Indonesian is apoteker, which was borrowed from the Dutch apotheker. In Yiddish the word is אַפּטייק apteyk.

Use of the term in the names of businesses varies with time and location. It is generally an Americanism, though some areas of the United States use it to invoke an experience of nostalgic revival and it has been used for a wide variety of businesses; while in other areas such as California its use is restricted to licensed pharmacies.

In Exodus 30:25 of the Bible the art of the apothecary is already mentioned. The profession of apothecary can be dated back at least to 2600 BC to ancient Babylon, which provides one of the earliest records of the practice of the apothecary. Clay tablets have been found with medical texts recording symptoms, prescriptions, and the directions for compounding.
