Alcester (ⁱ/ˈɒlstər/ or /ˈɔːlstər/) is an old market town of Roman origin at the junction of the River Alne and River Arrow in Warwickshire, England. It is situated approximately 8 miles (13 km) west of Stratford-upon-Avon, and 8 miles south of Redditch, close to the Worcestershire border. The 2001 census recorded a population of 6,214 in the town, which also has civil parish status.

In Roman times Alcester (Alauna) was a walled town and Roman fort of some importance^{[citation needed]} being located at a junction between the Ryknild Street Roman road and the ancient Saltway from Droitwich and the roman road from Stratford upon Avon and the Fosse Way.

An important market town, Alcester was the site of a Benedictine monastery founded in the middle of the 12th century by Ralph le Boteler. The monastery was once a thriving one. In 1318 Walter de Beauchamp, who had a seat in the neighbourhood, complained to the abbot of the monastery that some of his monks had removed Beauchamp's possessions from his manor. At the Dissolution, King Henry VIII granted the monastery to the Greville family.
