Sir Robert Travers was an Irish judge, soldier and politician of the early seventeenth century. Despite his unenviable reputation for corruption, he had a highly successful career until the outbreak of the Wars of the Three Kingdoms, when he went into opposition to King Charles I. He fought on the side of the Irish Parliament, and was killed at the Battle of Knocknanuss. He was a nephew of the poet Edmund Spenser, and was the founder of a notable military dynasty.

The Court of Castle Chamber was a Irish court of special jurisdiction which operated in the sixteenth and seventeenth centuries.
