Avening is a village and civil parish in the Cotswold district of Gloucestershire, England, about three miles north of Tetbury. According to the 2001 census it had a population of 1,094, decreasing to 1,031 at the 2011 census. The village has two pubs. Nearby is Gatcombe Park, the home of the Princess Royal.
During the Second World War, Avening lay on GHQ Line. Extensive anti-tank ditches were constructed to the south and southeast, and were overlooked by a number of pillboxes. The defences were constructed as a part of British anti-invasion preparations.
An electoral ward in the same name exists. This ward stretches from Avening in the west to Long Newnton in the south east. The total population of this ward taken at the 2011 census was 1,930.
Avening is also the name of a rural community immediately south of Creemore, Ontario, Canada, on the Mad River. One of its pioneers was Frederick C. Thornbury, who built a grist mill and a sawmill in the Ontario community in 1860, and named the settlement "after his native place in England".
