A manicure is a cosmetic beauty treatment for the fingernails and hands. A manicure treatment can be just for the hands or nails, or can be for both. A common manicure found is the filing, shaping of the nails and the application of polish. There are also manicure services that are specialties for the hands and feet. For the hands, the soaking of a softening substance and the application of a lotion is a common specialty. Another common specialty is applying this similar treatment of lotion to the feet, called pedicure. The word "manicure" derives from Latin: manus for hand, cura for "care".

Manicures often include the filing, polishing, and painting of fingernails. A manicure may also include the application of artificial nail tips, acrylics or artificial nail gels. Some manicures can include the painting of pictures or designs on the nails or applying small decals or imitation jewels.

In many areas, manicurists are licensed and follow regulation. Since skin is manipulated and is sometimes trimmed, there is a certain risk of spreading infection when tools are used across many people and therefore sanitation is a serious issue.
