The Highland Railway F class 4-4-0s were a class of British steam locomotives introduced in 1874. The first 10 were built by Dübs and Company in 1874. A further seven were built in Lochgorm works between 1876 and 1888. Originally they were the first Bruce class, and later became known as the Duke class to avoid confusion with the second Bruce class. As part of Peter Drummond's 1901 classification scheme they became class F.

The original batch had boilers pressed to 140 pounds-force per square inch (970 kPa), the later batch had slightly smaller boilers but a higher pressure of 150 lbf/in2 (1,030 kPa). Of typical Allan/Jones appearance, they had outside cylinders of 18 by 24 inches (457 by 610 mm).
Disposal
editWithdrawal commenced in 1907, and by 1909 all-but-one of the Dübs-built examples had been withdrawn. Numbers 31A and 74 were retired in 1913, number 71A was broken up in 1915. The remaining five survived until 1923 but none of them acquired a new London, Midland and Scottish Railway number.
