Dolores Ashcroft-Nowicki (born 11 June 1929) is a British occult author, psychic, and esoteric practitioner.
During the 1960s, she and her husband Michael Nowicki entered the Fraternity of the Inner Light, an esoteric order founded by occultist Dion Fortune. In 1965 she became associated with Walter Ernest Butler, and with Gareth Knight and the Helios Course in Practical Qabalah which, in 1971, became the foundation of Servants of the Light School. In 1976, when Butler retired, Ashcroft-Nowicki became Director of Studies of the Servants of the Light, a position she holds to this day.
