Rainbow Valley is the seventh book in the Anne of Green Gables series by Lucy Maud Montgomery. In this book Anne Shirley is married with six children, but the book focuses more on her new neighbor, the new Presbyterian minister John Meredith, as well as the interactions between Anne's and John Meredith's children.

The book is dedicated: "To the memory of Goldwin Lapp, Robert Brookes and Morley Shier who made the supreme sacrifice that the happy valleys of their home land might be kept sacred from the ravage of the invader." This refers to World War I, which is the main theme of the next and final book in the series, Rilla of Ingleside.
