Esther Johnson was an Englishwoman known to have been a close friend of Jonathan Swift, known as "Stella". Whether or not she and Swift were secretly married, and if so why the marriage was never made public, is a subject of debate.

Jonathan Swift was an Anglo-Irish satirist, author, essayist, political pamphleteer, poet, and Anglican cleric who became Dean of St Patrick's Cathedral, Dublin, hence his common sobriquet, "Dean Swift".
