"Neutron Star" is an English language science fiction short story written by Larry Niven. It was originally published in the August 1966 issue (Issue 107, Vol 16, No 10) of Worlds of If?. It was later reprinted in Neutron Star (1968, together with At the Core 1966, Flatlander 1967, Grendel 1968, The Handicapped, The Soft Weapon and A Relic of Empire) and in Crashlander (1994, together with At the Core 1966, Flatlander 1967, Grendel 1968, The Borderland of Sol 1975, Procrustes) . The story is set in Niven's fictional Known Space universe. It is also notable for including a neutron star before their (then hypothetical) existence was widely known.
"Neutron Star" is the first to feature Beowulf Shaeffer, the ne'er-do-well ex-pilot and reluctant hero of many of Niven's Known Space stories. It also marked the first appearance of the nearly indestructible General Products starship hull, as well as its creators the Pierson's Puppeteers. The star itself, BVS-1?, is featured in the novel Protector (1973), where it is named "Phssthpok's Star". A prelude to the story is also included in the novel Juggler of Worlds.
