Bowls (also lawn bowls, variants include flat-green bowls and crown-green bowls) is a sport in which the objective is to roll biased balls so that they stop close to a smaller ball called a "jack" or "kitty". It is played on a pitch which may be flat (for "flat-green bowls") or convex or uneven (for "crown-green bowls"). It is normally played outdoors although there are some indoor venues and the surface is either natural grass, artificial turf, or cotula (in New Zealand).

It is popular in the United Kingdom, Australia, New Zealand, Canada, South Africa, Hong Kong and parts of the United States and more recently in Japan. It belongs to the boules game family and is related to bocce and pétanque.
