October 1637 – 14 November 1706) was a Welsh politician who sat in the House of Commons in three periods between 1660 and 1689.
He inherited the baronetcy of Margam on the death of his brother Henry who died in infancy in around 1640.
The Duke of Beaufort, when Lord President of Wales, visited Margam during his "Progress" in 1684.
His son, Thomas, succeeded to the baronetcy and was created Baron Mansel.
His daughter Martha married Thomas Morgan of Tredegar, which marriage and its after-effects caused the baronet much trouble because Thomas Morgan was reluctant to return from a tour on the continent of Europe.
