The East Anglian Brigade was an administrative formation of the British Army from 1948 to 1968. The Brigade administered the regular infantry regiments of East Anglia, England.
After the Second World War the British Army had fourteen infantry depots, each bearing a letter. The depots were territorially organised, and Infantry Depot G at Colchester was the headquarters for the county regiments of Bedfordshire, Cambridgeshire, Essex, Hertfordshire, Huntingdonshire, Norfolk, Northamptonshire and Suffolk.
In 1948, the depots adopted names and this depot became the East Anglian Brigade, with all regiments being reduced to a single battalion at the same time. The East Anglian Brigade was formed on 14 July 1948 at Gibraltar Barracks, Bury St Edmunds as an administrative apparatus for the infantry regiments from East Anglia:
Under the Defence Review announced in July 1957, the infantry of the line was reorganised: In 1958, the Royal Lincolnshire Regiment was transferred from the Forester Brigade, and by 1960 the six individual regiments had amalgamated to form three "East Anglian Regiments":
At the same time East Anglian Brigade cap badges and buttons replaced those of the individual regiments. The cap badge was a silver eight-pointed star bearing the castle and key of Gibraltar, with a scroll inscribed "East Anglia". The key and castle was a badge awarded to predecessors of all three regiments for their part in the Great Siege of Gibraltar from 1779 - 1783. The brigade buttons were identical to those of the Royal Norfolk Regiment, bearing the figure of Brittania.
