The Great Northern Railway class C2 locomotives is a scrapped class of 4-4-2 tank locomotives built by the Great Northern Railway (GNR) between 1898 and 1907.

They were used on local and commuter passenger trains in Yorkshire and North London.

All passed to the London and North Eastern Railway in 1923, who renumbered them by adding 3000 to their GNR number.

In 1948, the remaining 49 locomotives passed to British Railways, who renumbered them by prefixing a 6 to their LNER number (i.e. 67350–67399).
