The Lancashire and Yorkshire Railway (L&YR) Class 7 was a class of Atlantic passenger steam locomotives to the design of John Aspinall. Forty were built between 1899 and 1902. They were known as "High-Flyers" as a result of having a high-pitched boiler that was supposed to increase stability at speed. All passed into London, Midland and Scottish Railway (LMS) ownership on the grouping of 1923, becoming the LMS's only atlantic tender engine class. The LMS gave them the power classification 2P. Withdrawals started in 1926, and the last was withdrawn in 1934. None was preserved.
