Listerine is a brand name for antiseptic mouthwash. Its original formula has a notoriously strong flavour, although variations have been released that are marketed as tasting milder. The product is marketed under the slogan "Kills germs that cause bad breath".
First formulated by Dr. Joseph Lawrence and Jordan Wheat Lambert in 1879 as a surgical antiseptic. The mouthwash was named in honour of Dr. Joseph Lister, an English surgeon, a pioneer of antiseptic surgery.
- 1879 Americans Dr. Joseph Lawrence and Jordan Wheat Lambert formulated their first disinfectant, naming it after Dr. Joseph Lister.

- 1921-1970s Listerine was also as a preventive and remedy for colds and sore throats.
- 1976 The Federal Trade Commission ruled that these claims were misleading, and that Listerine had "no efficacy" at either preventing or alleviating the symptoms of sore throats and colds. The Warner-Lambert Co was ordered to stop making the claims, and to include in the next $10.2 million dollars' of Listerine ads a specific mention that "contrary to prior advertising, Listerine will not help prevent colds or sore throats or lessen their severity."
- Listerine was packaged in a glass bottle inside a corrugated cardboard tube for nearly 80 years before the first revamps were made to the brand.

Currently, eight different kinds of Listerine are on the market in the U.S. and elsewhere: Original, Cool Mint, FreshBurst, Natural Citrus, Vanilla Mint, Advanced with Tartar Control (Arctic mint), Tooth Defense (mint shield), and Whitening pre-brush rinse (clean mint). The most recent addition is the Listerine Total Care, marketed as the Most Complete Listerine.
