Motto 'ROSA CONCORDIA SIGNUM' - The rose, emblem of harmony.
Granted 1st August 1939.

A rose has long been the emblem of Northamptonshire, having appeared on a seal used by the magistrates in Quarter Sessions as far back as 1665. The fetterlock and roses recall Northamptonshire's associations with the houses of York and Lancaster, whose rivalry culminated in the Wars of the Roses, and whose ultimate union was symbolized by the Tudor rose.
The silver falcon is derived from the heraldry of Edward III and his great great great great grandson Edward IV, who was linked to the county through his marriage at Grafton Regis to Elizabeth Woodville, a member of an ancient North­amptonshire family which supported the Lancastrian cause, and which is represented in the arms by the red rose. The white roses, the falcon, and the fetterlock are all Yorkist badges.
The black bull and the white hart are taken from the heraldry of the Yorkist Kings, and also refer to the county’s leather and shoe-making industries. The white hart also represents the ancient royal forests of Rockingham, Salcey and Whittlebury and its metal collar the steel industry.
This motto refers to the Tudor rose a combination of the white Yorkist and red Lancastrian roses.

The five red conjoined diamonds refer to the five former local authorities, whose areas were united in 1974 to form the current Borough. The diamonds derive from the arms of the Montagus of Boughton in whom part of the Manor of Kettering was vested. The gold pelt, like that in the arms of the former Borough of Kettering, the sheaf of wheat and the two silver cogwheels, refer to the marriage of the urban and rural areas of the Borough and represent the leather used in the footwear industry and its allied trades, agriculture and food production, which with engineering are the three main historical activities in the Borough.
The crest depicts Geddington Cross which is an outstanding historical monument in the Borough, and one of the three remaining Crosses erected by King Edward I at each place where the body of his wife Queen Eleanor of Castile rested overnight on its journey from Lincolnshire to Westminster Abbey in 1294. The heraldic fountains at both sides of the base of the Cross symbolises the formation of the Baptist Missionary Society at the Mission House in Lower Street, Kettering, in 1792.
