Crashlander is a fix-up novel by American writer Larry Niven, published in 1994 (ISBN 978-0345381682) and set in his Known Space universe.

Crashlander brings together the short stories featuring the space pilot Beowulf Shaeffer — "Neutron Star" (1966), "At the Core" (1966), "Flatlander" (1967), "Grendel" (1968), "The Borderland of Sol" (1975), and "Procrustes" (1993).

Ander, working for ARM agent Sigmund Ausfaller, has come to question him about his dealings with Pierson's Puppeteers, General Products and Carlos Wu, as well as what happened to Wu and ARM agent Feather Filip.

Wu, Shaeffer and Sharrol Janss and their children, Tanya and Louis Wu, had secretly emigrated from Earth to the planet Fafnir to escape the control of Earth's United Nations government and the ARM.

Most of the stories in the collection are retold from the point of view of Sigmund Ausfaller in Juggler of Worlds.
