Kathryn Mary Paterson (17 October 1962 – 20 September 1999) was the ninth Chief Censor of New Zealand and a Director of Australia's Office of Film and Literature Classification.
She was New Zealand's ninth Chief Censor, and the first appointed under the new Films, Videos, and Publications Classification Act 1993.
This Act gave the Office of Film and Literature Classification jurisdiction to classify a broader range of publications than was possessed by her predecessor as Chief Censor, Jane Wrightson, whose jurisdiction was limited to the classification of films for public exhibition.
When she was appointed Chief Censor, the opposition women's affairs spokesperson Elizabeth Tennet MP raised fears that Paterson would import Australian "macho cultural imperialism" into New Zealand.
In December 1998, Paterson returned to Sydney to become director of the Australian Office of Film and Literature Classification, a position she held until her death from cancer ten months later on 20 September 1999.
