Portsmouth Harbour is an 1831 landscape painting by the British artist Clarkson Stanfield.

Prominent inside the harbour is HMS Victory, Lord Nelson's flagship during the Battle of Trafalgar.

[2] The new monarch William IV had seen Stanfield's 1830 work Mount St Michael, Cornwall at the Royal Academy's Summer Exhibition at Somerset House.

Impressed, he commissioned two works from the painter including this view of Portsmouth.

A sailor in his youth, and recently having served as Lord High Admiral, William maintained a strong association with the Royal Navy.
