The Circus is a historic street of large townhouses in the city of Bath, Somerset, England, forming a circle with three entrances. Designed by the prominent architect John Wood, the Elder, it was begun in 1754, completed in 1768, and is regarded as a preeminent example of Georgian architecture. The name comes from the Latin 'circus', which means a ring, oval or circle. It has been designated as a Grade I listed building.

The Circus is divided into three segments of equal length, with a lawn in the centre. Each segment faces one of the three entrances, ensuring a classical facade is always presented straight ahead.

The Circus, originally called King's Circus, was designed by the architect John Wood, the Elder. Convinced that Bath had been the principal centre of Druid activity in Britain, Wood surveyed Stonehenge, which has a diameter of 325 feet (99 m) at the outer earth bank, and designed the Circus with a 318 feet (97 m) diameter to mimic this.

Wood died less than three months after the first stone was laid; his son, John Wood, the Younger, completed the project to his father's design. The initial leases for the south west segment were granted in 1755 - 67, for the south east segment in 1762 - 66, and for the north segment in 1764 - 66.
