Phylogenesis (1999) is a science fiction novel by American writer Alan Dean Foster. It is the first novel in Foster's Founding of the Commonwealth Trilogy.

In Phylogenesis, Foster begins to further expand the history of the founding of the Humanx Commonwealth, which began in his 1982 novel Nor Crystal Tears. While Nor Crystal Tears was a first contact novel between human and thranx, and set the foundation for the eventual Humanx Commonwealth, starting with Phylogenesis, Foster's trilogy set out to detail the events that led to the union between the two races.
