Lewisham East is a parliamentary constituency in South London represented in the House of Commons of the UK Parliament since the by-election on 14 June 2018 by Janet Daby of the Labour Party.

[2] The constituency stretches from Blackheath, which has more in common with the more affluent areas of the Royal Borough of Greenwich (which contains the north and east parts of Blackheath)[3] to the wards to the south of the constituency which contain more social housing and less architectural grandeur.

At the southern end of the constituency is Grove Park, one of the quieter and more prosperous parts of Lewisham, which is more marginal between Labour and the Conservatives than the rest of the borough.

Some wards in the constituency are steadily increasing in average income and median age, and thus have become Conservative targets in local elections.

Lewisham East had the 51st largest Labour vote share in the country at the 2015 election, out of 650 constituencies.
