The poems listed here are from various writings of Tolkien.  Although the majority can be found in The Hobbit or LotR, some come from The Tolkien Reader.  Of course, I do plan on adding more in the future.   Note that not all the poems in Tolkien's writings have names.  I have given names to those that were without so as to make a distinction of it.

Goldberry

O slender as a willow-wand! O clearer than clear water!
O reed by the living pool! Fair River-daughter!
O spring-time and summer-time, and spring again after!
O wind on the waterfall, and leaves' laughter!
