Patrick Finglas (died 1537) was a leading Irish judge and statesman of the sixteenth century, who was regarded (except perhaps in his last years) as a mainstay of the English Crown in Ireland. He was also the author of an influential "Breviat", or tract, called Of the Getting of Ireland, and of the Decay of the same, concerning the decline of English power in Ireland.
Little is known of his parentage, but Francis Elrington Ball states that he came from a long-established family who lived in and took their surname from Finglas, County Dublin. He later held estates at Piercetown, near Dunboyne, County Meath, and at Westphailstown (or Westpalstown) in County Dublin, which became the principal family residence. He was at Lincoln's Inn 1503-6 and became Serjeant in 1509. He was considered one of the ablest lawyers of his time, and also a gifted writer on politics.
