John Bettes the Younger (died 1616) was an English portrait painter.
Like Isaac Oliver and Rowland Lockey, Bettes the Younger is believed to have studied under Nicholas Hilliard.
A miniature portrait of Francis Walsingham, who was buried at St Gregory's Church in 1590, in the possession of the Duke of Buccleuch is attributed to Bettes.
John Bettes and his studio are thought to have made a number of portraits of Elizabeth I.
A son, Thomas Bettes, died in August 1593, and a daughter Judith was born in July 1599.
