The Problem of Ros is the twelfth chapter of The Peoples of Middle-earth.

The chapter is dedicated to a 1968 linguistic essay by J.R.R. Tolkien, concerning the word ros, as seen in the name Cair Andros.

While writing it, Tolkien realised that what he is explaining had already a solution in the Appendices, and rejected "most of it".
