The Hanover is believed to have been built during the reign of George I as accommodation and included stablingfor horses. This area of Harwich was known as Hanover Square and was used by merchants, the Hanover sat in the South-Western corner of the square.

It was known as dining rooms and an inn in the 1850s, becoming licensed for ale and cider at the same time.

In October 1888 the Hanover was almost destroyed when a paraffin lamp fell onto furniture and a rug, setting fire to tothe Dining Room. Only the swift action of the landlord of the time, William Lawrence, prevented a tragedy. A dairy was attached to the Hanover at this time as the landlord owned a herd of cows, which grazed on the slopes of the Redoubt Fort.

In more recent times the Hanover was acquired by the mighty Cobbold empire, and became a Tolly Cobbold pub when the Ipswich brewers merged in 1957. Around this time the Hanover became fully licensed so it could serve wines and spirits in addition to beer.

When Tolly Cobbold collapsed in 1989 the Hanover became a free-house. It is currently owned by Rob & Teresa Ranson.

The Hanover Inn is Grade II listed.
