Louisa Berkeley, Countess of Berkeley (née Lennox; 24 December 1694 – 15 January 1716) was the first wife of James Berkeley, 3rd Earl of Berkeley. Her father Charles was an illegitimate child of King Charles II, thus making her the king's granddaughter.

Louisa married the Earl of Berkeley on 13 February 1711. At the time of her wedding, Jonathan Swift said of her: "the chit is but 17 and is ill-natured, covetous, vicious and proud in extremes."
They had two children:

Lady Elizabeth Berkeley (15 January 1716 - died 1745), who married Anthony Henley
