Members of the British National Front (NF) clash with anti-NF demonstrators in Lewisham, London, resulting in 214 arrests and at least 111 injuries.

The National Front (NF) is a far-right, fascist political party in the United Kingdom. It is currently led by Tony Martin. A minor party, it has never had its representatives elected to the British or European Parliaments, although it gained a small number of local councillors through defections and it has had a few of its representatives elected to community councils. Founded in 1967, it reached the height of its electoral support during the mid-1970s, when it was briefly England's fourth-largest party in terms of vote share.

The Battle of Lewisham took place on 13 August 1977, when 500 members of the far-right National Front (NF) attempted to march from New Cross to Lewisham in southeast London but were met by various counter-demonstrations of approximately 4,000 people that led to violent clashes between the two groups and between the anti-NF demonstrators and police. 5,000 police officers were present, and 56 officers were injured, 11 of whom were hospitalised. In total, 214 people were arrested. Later disturbances in Lewisham town centre saw the first use of police riot shields on the UK mainland.
