Judge Cassandra Anderson is a fictional law enforcer and psychic appearing in the British science fiction comics 2000 AD and the Judge Dredd Megazine. Created by writer John Wagner and artist Brian Bolland, Anderson made her debut as a supporting character in the Judge Dredd story "Judge Death". The character's popularity with readers led to her starring in her own series, Anderson: Psi-Division, which has been written almost exclusively by Alan Grant, often working with artist Arthur Ranson until 2005; Boo Cook drew a majority of the stories until 2012, since which a number of different artists have worked on the strip. In 2012, the character appeared in the film Dredd, played by Olivia Thirlby.

John Wagner is an American-born British comics writer. Alongside Pat Mills, he helped revitalise British comics in the 1970s, and continues to be active in the British comics industry, occasionally also working in American comics. He is the co-creator, with artist Carlos Ezquerra, of the character Judge Dredd.
