A wet wipe, also known as a wet towel, or a moist towelette, is a small moistened piece of paper or cloth that often comes folded and individually wrapped for convenience. Wet wipes are used for cleaning purposes, like personal hygiene or household cleaning.

Wet wipes are produced as air-laid paper where the fibres are carried and formed to the structure of paper by air or with nonwoven spun-lace fabric where fibers are intermingled with hydro entanglement through very high pressure of water. They are moistened with water or other liquids like isopropyl alcohol depending on the applications. The paper might be treated with softeners, lotions or added perfume to adjust the properties or "feeling". Preservatives such as methylisothiazolinone are used to prevent bacterial or fungal growth in the package. The finished wet wipes are folded and put in pocket size package or a box dispenser.

Wet wipes can serve a number of personal and household purposes. Although marketed primarily for wiping infants' backsides in diaper changing, it is not uncommon for consumers to also use the product to clean floors, toilet seats, and other surfaces around the home. Parents also use wet wipes, or as they are called for baby care, baby wipes, for wiping up baby vomit and to clean babies' hands and faces.
