The Bellarmine Jug (1984) is a novel by Australian writer Nicholas Hasluck.

[1] In 1948 a student lawyer at the Hague discovers that the Dutch Government has potentially covered up the true story, and political implications, of the Batavia, a Dutch ship which was wrecked on a small island off the west coast of Australia in 1629.

The resultant orgy of murder became known as one of the "worst horror stories in maritime history".

Writing in The Canberra Times reviewer Susan McKernan noted: "Nicholas Hasluck's fourth novel is an historical mystery enclosed in a spy story," although the novel "despite the elements of mystery and thriller, is concerned with more abstract legal questions.

Hasluck is more interested in the balance between justice for the individual and the good of the state.
