Elizabeth Katayama (1912 ? 4 September 1998) was an Australian writer under the pseudonym Elizabeth Kata, best known for Be Ready with Bells and Drums (1961), which was made into the award-winning film A Patch of Blue (1965).

As well as writing novels, she also wrote for television and several Hollywood scripts. Her first novel, Be Ready with Bells and Drums (written in 1959, first published in 1961), was produced as the film A Patch of Blue (1965). Shelley Winters playing the role of Rose-Ann D'Arcey won an Academy Award for Best Actress in a Supporting Role. Guy Green, who directed, also adapted Kata's book and his screenplay was nominated for a Writers Guild of America award. After the success of the film, the novel was re-released as A Patch of Blue. The book was for many years included in the "school book list" both in the US and Australia. The book Mrs Katayama and Her Splash of Blue (2010, Independence Jones), covers how Elizabeth Kata's first book became the film A Patch of Blue.
