John Baxter the Younger (died 1798), was a Scottish architect active in the 18th century. He was the son of Edinburgh master mason, John Baxter (died around 1770) and was sent, along with his brother, Alexander Baxter, to Italy by him in 1761 to study architecture. In March 1766 Baxter became a full member of St. Luke's Academy. Soon after returning to Scotland, he took over his father's business in Edinburgh and from around 1769 began working on plans and alterations for several country houses and other buildings in Scotland. Baxter died in Edinburgh in July 1798.
