Batty Langley (baptised 14 September 1696 – 3 March 1751) was an English garden designer, and prolific writer who produced a number of engraved designs for "Gothick" structures, summerhouses and garden seats in the years before the mid-18th century.
An eccentric landscape designer, he gave four of his sons the names Hiram, Euclid, Vitruvius and Archimedes. He published extensively, and attempted to "improve" Gothic forms by giving them classical proportions.
