Star Maker is a science fiction novel by Olaf Stapledon, published in 1937. The book describes a history of life in the universe, dwarfing in scale Stapledon's previous book, Last and First Men (1930), a history of the human species over two billion years. Star Maker tackles philosophical themes such as the essence of life, of birth, decay, and death, and the relationship between creation and creator. A pervading theme is that of progressive unity within and between different civilizations.

Some of the elements and themes briefly discussed prefigure later fiction concerning genetic engineering and alien life forms. Arthur C. Clarke considered Star Maker to be one of the finest works of science fiction ever written. The narrative is a contemplative journey through space and time, exploring how galaxies of stars formed from nebulae, how planets came into existence, and how intelligent life evolved. The book provides a profound perspective on mankind's existence in universal time and space.

There are touching moments and exciting battles, both tragedy and comedy. Uplifting victories and crushing defeats fill the pages, making this book a very engaging read. The final chapters provoke deep ponderings about life and intelligence, leaving the reader with lifelong questions to mull over.
