Earl of Gainsborough is a title that has been created twice, once in the Peerage of England and once in the Peerage of the United Kingdom. The first creation ended in extinction when the sixth Earl died without heirs. However, the title was revived in 1841 for a female-line relative.

Baptist Hicks, 1st Viscount Campden was an English cloth merchant and politician who sat in the House of Commons between 1621 and 1628. King James I knighted Hicks in 1603 and in 1620 he was created a baronet.
