Gloucester Green is a square in central Oxford, England, and the site of the city's bus station.

From 1783 to 1915 a fair was held on the green, and from 1835 to 1932 it was the site of the city's cattle market.

In 1935, after the cattle market had been moved, the western half of Gloucester Green became the site of the city's bus station, and the eastern half became a car park.

The eastern half became a square, surrounded by shops, restaurants and residential accommodation.

Today, the Gloucester Green bus station is the Oxford terminus for long-distance coach services, including services to London, coaches to Heathrow, Gatwick, Luton and Stansted airports, and route X5 to Cambridge.
