Julia Clara Catherine Maria Dolores Robins Norton Birk Olsen Hitchens, better known as Dolores Hitchens, was an American mystery novelist who wrote prolifically from 1938 until her death. She also wrote under the pseudonyms D.B. Olsen, Dolan Birkley and Noel Burke.

Hitchens collaborated on five railroad mysteries with her second husband, Bert Hitchens, a railroad detective, and also branched out into other genres in her writing, including Western stories. Many of her mystery novels centered around a spinster character named Rachel Murdock.

Hitchens wrote Fool's Gold, the 1958 novel adapted by Jean-Luc Godard for his film Bande à part (Band of Outsiders, 1964).

Although she was known as Julia as a child, she later said Dolores was the only one of her five given names she liked. Robins was her maiden name; Norton and Birk were two previous stepfathers; Olsen was her first husband; and Hitchens was her second husband.
