The County of Avon was formed in 1974 from the City of Bath, the City and County of Bristol, the southern part of the County of Glocestershire and the northern part of the County of Somerset. It was abolished in 1996.

The six blue and white waves represent the River Avon, from which the County derived its name, and its six constituent districts. They are also indicative of the Severn and the coastal areas. The dragon is associated with both Wessex and Celtic Britain and Avon has historical links with both cultures. The Wessex dragon is sometimes red, as in the arms of the Somerset and Wiltshire County Councils, sometimes gold, as in those of the Dorset County Council and several civic authorities in the area. The British dragon is red also. The dual link is thus represented by the dragon divided into gold and red by a chevron-shaped partition line, derived from the Gloucestershire shield.
The wreath and mantling are in white and blue, the heraldic colours for water as seen in the six Avon waves in the Shield. The crest combines the unicorn of Bristol with the sword of St. Paul (one of the patron saints of Bath Abbey) and the crown of King Edgar, who was crowned King of all England by St. Dunstan in Bath Abbey on Whit Sunday AD 973. The sword and crown also occur in the arms of Bath.
The sea-stags, never before used in civic heraldry, represent the fusion of two characteristic features of Avon - sea and forest. The historic importance of the Avon ports is linked with that of the Royal Forests which covered a large part of the County. Each stag is a "stag royal", i.e. with six tynes on each antler, and has about the neck an ancient crown of fleurs-de-lys to emphasise the royal associations. The heraldic fountains again represent the rivers and springs of the County.
The special compartment represents the Cotswold and Mendip hills, with the River Avon running between.

The Kingswood District was formed by the amalgamation of the Kingswood Urban District, the Mangotsfield Urban District and the Warmley Rural District. It was abolished in 1996.

The design includes many features of the arms of the former Kingswood UDC. The green background is symbolic of the forest which once covered a substantial part of southern England, the golden stag wearing the Plantagenet Crown of Henry III serving as a reminder of Kingswood's associations with the Royal hunt at a time when the area was known as the King's Chase. The chain worn by the royal stag represents the location of the new Kingswood in the King's Chase. The crown of fleurs de lys and colours of the mantling have been taken from the former Kingswood arms and the basic colours of green and gold, have been used to perpetuate the symbolism of the Chase.
The golden lion represents the Royal lions of England and the crown and chain it is wearing are linked with those worn by the stag. The sprig of oak with three acorns symbolises the union of the former Kingswood and Mangotsfield Urban District Councils and Warmley Rural District Council to form Kingswood District Council. The torch represents progress and is coloured black to represent the coal mining industry which once dominated the area.

The Northavon District was formed by the amalgamation of part of the Sodbury Rural District and part of the Thornbury Rural District. It was abolished in 1996.

The shield combines the principal emblems from the arms of the former Sodbury and Thornbury Rural District Councils. The white background is like that of the arms of the Sodbury RDC. The green wave represents the Vales of Berkeley and Sodbury, its edges suggesting the Rivers Severn and Frome. The two gold wheatsheaves represent the agriculture of the two Rural Districts and between them a pair of gold wings, taken from the arms of the Thornbury RDC, alludes to the important aircraft industry at Filton and Patchway. Above the wave is one of the red lions from Sodbury's shield, and below is the punning "Thorn-berry" tree from the crest of Thornbury.
The battlements of the crest recall the historic associations of Thornbury Castle and out of these rises the white crosslet of the Howards, entwined with a gold Stafford knot.
The green wyvern and cockatrice repre­senting respectively the Beaufort and the De la Warr families. Each supporter holds one of the gold clarions from Sodbury's shield, taken from the arms of Keynsham Abbey which once held the manor of Marshfield. These clarions were also the arms of the Cranvilles and provide a passing reference to the Battle of Lansdown from which Sir Basil Cranville was carried, mortally wounded, to Cold Ashton.
