John Baillie (10 May 1806 – 29 October 1859) was an English mechanical engineer who worked mainly in Austria and Germany.
John Baillie was born in Newcastle-upon-Tyne, England, on 10 May 1806.
He joined the Emperor Ferdinand Northern Railway (Kaiser-Ferdinands-Nordbahn or KFNB) in 1836 when the locomotives ordered by the company from George Stephenson arrived and instructed the Austrian staff of the KFNB on the locomotives.
In 1846 he invented the Baillie Schneckenfeder, a type of coiled spring named after him, which was fitted to the buffers of railway vehicles.
