The A33 is a major road in England, situated in the counties of Berkshire and Hampshire. The road currently runs in three disjoint sections.

The A33 currently starts on the Inner Distribution Road and bypasses most of suburban Reading, servicing the Kennet Island residential development, Madejski Stadium and Green Park Business Park, towards the M4, where it connects at junction 11. A two-year redevelopment scheme ran from early 2008 until late 2010, widening the northern section of the dual carriageway and significantly expanding and improving the motorway junction. The Mereoak Roundabout south of the motorway was replaced with two separate junctions with traffic lights.

The section south of the M4 is dual carriageway up to the county boundary with Hampshire, where it reverts to single carriageway towards Basingstoke.

The second section of the A33 starts near Popham, southwest of Basingstoke at a junction with the A30. The road from here to Winchester is a scenic mix of single and dual carriageway, that was progressively improved in the late 1960s. The route runs through much of the borough of Basingstoke and Deane. At Kings Worthy, the road diverts onto part of the original Winchester Bypass, constructed in the late 1930s, up to the A34.
