Snus (/ˈsns/; Swedish pronunciation: ) is a moist powder tobacco product originating from a variant of dry snuff in early 18th-century Sweden. It is placed under the upper lip for extended periods. Snus is not fermented and contains no added sweeteners. Although used similarly to American dipping tobacco, snus does not typically result in the need for spitting and, unlike naswar, snus is steam-pasteurized.

Snus is commonly sold in the Nordic countries but sale is illegal in all the European Union except Sweden. Local varieties of snus, growing in popularity in the United States, have been seen as an alternative to smoking, chewing, and dipping tobacco. However, US-manufactured snus does not have the same production standards or ingredients as Swedish snus, and typically uses significant amounts of sweeteners.

Snus usually contains nicotine, which is highly addictive, and is harmful to health. The chemical constituents of different types of snus vary, and population-level studies suggest that the risks do, too.

In the 16th century, snuff (pulverized tobacco), the precursor of snus (moist snuff), was introduced to France by French diplomat Jean Nicot, who worked at the court of King Henry II of France. He recommended snuff to Catherine de' Medici as a migraine remedy. When she became a regular user of snuff, it became a fashion among the court and upper-class citizens of France, especially among females, as it was deemed more socially acceptable than other forms of tobacco.

This trend of using snuff in the nose also spread to Sweden at the beginning of the 17th century. In the 19th century, Swedish producers began to manufacture moist snuff, which was placed under the upper lip and did not require spitting. It became known as snus. Ettan (meaning "the number one"), registered since 1822, is the oldest brand of snus still sold.

It is a popular myth that snus or any other forms of smokeless tobacco contains fiberglass, or glass particles, as an aid to the absorption of nicotine by the user's blood. This is not true. Mucous membranes readily absorb free nicotine. The burning sensation is caused by the nicotine itself (similar to the tingle of nicotine gum) and some food additives such as sodium carbonate (E500). Sodium carbonate is a food additive used to increase the pH of the tobacco (reduce the acidity). This increases the bioavailability of the nicotine, meaning more is available for absorption. Some flavorings (mints in particular) are astringent and may increase the tingling or burning sensation.
