What is a group of horses called?

A group of horses is called a herd.

Herd is the standard collective noun for horses, whether they are domestic animals on a farm or free-roaming horses living together. Horses are social herd animals: they form stable relationships, communicate through body language and sounds, and often follow a social hierarchy led by experienced individuals.

Living in a herd offers several advantages. More animals can watch for danger, while others rest or feed. Groups can also make it easier for young horses to learn movement, social signals, and suitable feeding areas. Domestic horses may still show these instincts even when they live in paddocks or stables.

Other terms appear in specialized contexts. A string can mean a group of horses owned or ridden by one person, while a remuda is a ranch’s group of saddle horses. A team usually refers to horses working together, especially to pull a vehicle. These words do not replace herd as the ordinary answer.
