Robert Thomas Cross (born 15 May 1850 in Worstead, d. 1923) was a British astrologer.
He began studying astrology quite young and by the age of twenty-five, already married with two sons, he was teaching astrology and accepting clients, and soon became the editor of The Prophetic Messenger, which he renamed to Raphael's Ephemeris.
In the 1870s he obtained the copyright to Raphael's Ephemeris, which the Cross family then owned until 1985 when it was sold to W. Foulsham & Co, the publisher.
On 14 January 1896 Alan Leo founded a society with himself as the first president and Cross as vice-president.
A followup book under the pseudonym Raphael titled The Key To Astrology was published in 1896.
