The Bavarian C III engines were steam locomotives of the Royal Bavarian State Railways (Königlich Bayerische Staatsbahn).

[1] The standard variant of the C III was developed from the Class C II.

A total of 239 examples were built, which varied somewhat in their dimensions.

For example, the third batch had a boiler diameter 30 mm greater than the others.

Following a subsequent exchange of the boiler they were identical with other vehicles of this class apart from their overall weight.
