Sir John Dean Paul, 1st Baronet, of Rodborough, was an English landowner, banker, painter, and occasional author.

Most of Paul’s works as a painter were landscapes and paintings of horses. In 1821 he was created a baronet, a revival of an honour previously held by another branch of the Paul family.

By his wife, Frances Eleanor Simpson, daughter of John Simpson, of Bradley Hall, Co. Durham, and Lady Anne Lyon, Paul was the father of Sir John Dean Paul, 2nd Baronet (1802–1868), banker and fraudster. Frances, Lady Paul was the sister of the Baroness Ravensworth, as well as the niece of the Baroness Bradford and also a cousin of Lt Gen Sir Frederick Lester.

He died in 1852 and was buried in Kensal Green Cemetery, where his mausoleum was designed by John Griffith, the architect of the main cemetery buildings.
