Constance Georgina Louise Wachtmeister (née de Bourbel de Montpinçon; 1838-1910), known as Countess Wachtmeister, was a prominent theosophist, a close friend of Helena Blavatsky.

She was the daughter of a French marquis, but she was orphaned at an early age. She was raised in England by a maternal aunt. She married the Swedish politician Carl Wachtmeister, who was also her cousin. As a widow, she returned to England and joined the London Lodge of the Theosophical Society. Wachtmeister partnered with Blavatsky to work on The Secret Doctrine, and later organized a publishing company to publish Blavatsky's works. A memoir of her working relationship with Blavatsky was published posthumously, and has been used as a primary source for Blavatsky's biographers. (Wikipedia)
