Charles Locke Eastlake (11 March 1836 – 20 November 1906) was a British architect and furniture designer. His uncle, Sir Charles Lock Eastlake PRA (born in 1793), was a Keeper of the National Gallery, from 1843 to 1847, and from 1855 its first Director, which results in some confusion between the two men, whose names are distinguished only by the presence or absence of an "e" in their middle names.
