Bowls (lawn bowling) is a sport in which the objective is to roll slightly asymmetric balls, called bowls, so that they stop close to a smaller—normally white—bowl called the "jack" or "kitty". Bowls, either flat- or crown-green, is usually played outdoors, on grass and synthetic surfaces. Flat-green bowls can also be played indoors on synthetic surfaces. Both variants are collectively known as "lawn bowls".

Bowls belongs to the boules sport family, and so is related to bocce and pétanque. It is most popular in Australia, New Zealand (where the natural playing surface is cotula), the United Kingdom, and in other Commonwealth nations.

Lawn bowls is usually played on a large, rectangular, precisely leveled and manicured grass or synthetic surface known as a bowling green which is divided into parallel playing strips called rinks.
