Countess Wear is a district within the city of Exeter, Devon, England. It lies about two miles south-east of the city centre, on the north bank of the estuary of the River Exe. Historically an estate known as Weare, part of the manor of Topsham, was in this area. From the late 13th century, the construction of weirs in the River Exe by the Countess, and later, the Earls of Devon damaged the prosperity of Exeter to the benefit of Topsham which was downstream of the obstructions, and was owned by the Earls.
The bridges over the river and the adjacent Exeter Ship Canal were for many years a traffic bottleneck, until the completion of the last section of the M5 motorway, further downstream, in 1977.
