Lithuanians in the United Kingdom (Lithuanian: Didžiosios Britanijos lietuviai) include individuals born in Lithuania who have migrated to the UK, among them Lithuanian citizens of Russian descent and Polish Lithuanian citizens, as well as their British-born descendants. The 2011 UK Census recorded 95,730 Lithuanian-born residents in England, 1,353 in Wales, 4,287 in Scotland, and 7,341 in Northern Ireland. The previous, 2001 UK Census, had recorded 4,363 Lithuanian-born residents. The Office for National Statistics estimates that 144,000 Lithuanian-born immigrants were resident in the UK in 2013.
Significant numbers of Lithuanians came to the UK after Lithuania's European Union accession in 2004; however, there have been historically notable Lithuanian communities in the UK since the early 20th century — most notably in Scotland (Glasgow and the mining communities of North Lanarkshire and Midlothian) and London. The East London suburb of Beckton became known by some as "Little Lithuania" and "Bektoniškės" in the late 2000s, due to its Lithuanian diaspora presence.
