Progress Theatre is a local theatre company at Reading in England. It is a registered charity and it is a member of the Little Theatre Guild (LTG) and the National Operatic and Dramatic Association (NODA).

Progress Theatre was established in 1946^{[citation needed]} with the aim of presenting new and challenging work.^{[citation needed]}

Its first production was staged in 1947 in Palmer Hall, West Street, Reading. It moved to its present location, The Mildmay Hall, The Mount (near Reading University) in 1951.

In 1964, after a fund raising campaign, the freehold of the building was bought. After modernisation, the theatre now seats 97 people.

Kenneth Branagh, who was a member of the theatre in the late 1970s, became Progress Theatre patron in 2011.

In the 1950s a Student Group for 14- to 18-year-olds was set up. A charitable organisation, "The Progress Theatre" was established in 1962 with the object of promoting education in performing arts in Reading and the surrounding area. Since 2009, the Progress Youth Theatre consists of two groups for 15- to 18-year-olds and groups for school years 4 to 6 (ages 8 to 11), 7 to 8 (ages 11 to 13) and 9 to 10 (ages 13 to 15). The groups give a public performance each year.

The theatre has a membership of around 150 people and puts on a regular menu of classic and contemporary theatre. All of these productions are managed by volunteers.

The theatre also stages a summer open-air event, predominantly a Shakespeare play, at the historic and newly renovated ruins of Reading Abbey. These productions are managed in partnership with Reading Borough Council. In 2007, the event was expanded to form the Reading Abbey Ruins Open Air Festival. Due to the ongoing restoration of the abbey, in 2011 the event temporarily moved to the gardens of Caversham Court, the site of a Tudor manor house on the banks of the River Thames. However, it returned to Reading Abbey Ruins in 2018, following the completion of the renovations, and continued to perform from this beautiful location.
