Baron Bellew of Duleek was a title in the Peerage of Ireland.
It was created on 29 October 1686 for Sir John Bellew, as a reward for his support for James II.
He was outlawed after the Glorious Revolution and the accession of William and Mary, a decision that was later reversed on 30 March 1697.
The latter was twice returned to parliament for Steyning, but was unseated both times.
The title became extinct on the death of his son, the fourth Baron, in 1770.
