Stephen Geary was an architect active, particularly in London, England, in the early- to mid-19th century.
Geary studied art, then became an entrepreneur and produced fantastical architectural schemes, obtaining an outlet through cemetery designs. For the latter, he is perhaps best known for his work at Highgate Cemetery in London (opened 1839). He is also noted to have designed the first gin palace in that city in around 1830.
Geary died on 28 August 1854. He was buried in the cemetery of which he was the architect, Highgate. A tombstone there commemorates his life.
