Wyeth was a pharmaceutical company purchased by Pfizer in 2009. The company was founded in Philadelphia, Pennsylvania, in 1860 as John Wyeth and Brother. It was later known as American Home Products before being renamed to Wyeth in 2002. Its headquarters moved to Collegeville, Pennsylvania, and Madison, New Jersey, before its headquarters were consolidated with Pfizer's in New York City after the 2009 merger. The infant and maternal nutrition business was acquired by Nestlé in 2012.

Wyeth manufactured over-the-counter (OTC) drugs Robitussin and the analgesic Advil (ibuprofen) as well as prescription drugs Premarin and Effexor.

In 1860, pharmacists John (1834–1907) and Frank Wyeth opened a drugstore with a small research lab on Walnut Street in Philadelphia. In 1862, on the suggestion of doctors, they began to manufacture large quantities of commonly ordered medicines. They were successful, and in 1864 they began supplying medicines and beef extract to the Union army during the Civil War.

In 1872, Henry Bowers, an employee of Wyeth, developed one of the first rotary compressed tablet machines in the United States. This enabled the mass production of medicines with unprecedented precision and speed. It was successful, and the Wyeth brothers won multiple awards at the Centennial Exhibition. In 1883, Wyeth opened its first international facility in Montreal, Canada, and began vaccine production. Six years later a fire destroyed the brothers' original Walnut Street store, and they sold the retail business and focused on mass production. Cobalt blue glass bottles embossed with either "Wyeth" or "John Wyeth & Brother" in the glass are among the most popular antique bottles sought after by collectors.
