Tide is the name of a popular laundry detergent on the market in the United States and Canada. It is manufactured by Procter & Gamble.

First introduced in test markets in 1946 with national distribution reached in 1949, Tide was touted as "America's Washday Favorite". It quickly gained dominance in the detergent market, dwarfing the sales of its own products (such as Ivory Snow) as well as the competition (Rinso). The latter two were soap products.

Tide is recognized for its distinctive orange-and-yellow bullseye logo. Tide was the first product to be nationally packaged using Day-Glo colors, strikingly eye catching when first introduced. The logo people see today was a product of a slight modification for the product's fiftieth anniversary in 1996. Currently, the Tide brand is given to over half a dozen powders and liquid detergents in the United States alone.
