Llana of Gathol is a collection of four science fantasy stories by American writer Edgar Rice Burroughs, which were originally published in Amazing Stories in 1941. The first collected edition of Llana of Gathol was published in 1948 with an apparently new foreword. It is the penultimate book in the Barsoom series and the last to be published during Burroughs's lifetime. The stories in Llana of Gathol have a somewhat more humorous tone than earlier entries of the Barsoom series, and this book is considered to be an example of Burroughs engaging in self-parody late in his career.
