John Worth, B.D. (1648-1688) was an Irish Anglican Dean.^[1]

The son of Bishop Edward Worth,^[2] and Susannah Pepper, daughter of Denis Pepper, a cousin of the Earl of Cork, and brother of the noted judge William Worth, he was educated at Trinity College, Dublin.^[3] He was appointed a prebendary of Killaloe in 1670;^[4] Chancellor of St. Patrick's Cathedral, Dublin in 1671;^[5] Dean of Kildare in 1675;^[6] and Dean of St. Patrick's Cathedral, Dublin in 1678.^[7] He died on 12 April 1688.^[8]

Religious differences played a large part in his own early life. His father was a Protestant of strongly Puritan leanings, with no sympathy for either Baptists or Quakers. His mother on the other hand was a Quaker who was arrested in 1664 for publicly attending Quaker meetings. This caused a breach between the couple which was never healed: in his last will his father urged his mother to repent for her unorthodox beliefs.

His wife's first name was Comfort: they had ten children. Only two are known to have survived into adulthood, Michael and Edward Worth (1678-1733), the noted physician and book collector.
