The Remarkable Adventures of Lancelot Biggs, Spaceman (sometimes referred to as Lancelot Biggs: Spaceman) is a collection of humorous science fiction stories by Nelson Bond, published by Doubleday Books in 1950.

It comprises eleven of the fourteen stories in Bond's "Lancelot Biggs" series.

[1] The Index to Science Fiction Anthologies and Collections incorrectly lists "The Scientific Pioneer Returns" as one of the volume's included stories.

Its reviewer commented that "Author Nelson Bond, who used to write westerns, has merely put a Space Age icing on the old Wild West conventions" and that "to those who have never exposed themselves to the comic strips, the pseudo-scientific gobbledygook that spews forth from every page of Lancelot Biggs: Spaceman may cause some confusion for a while [although] [t]he persistent will get the hang of it.

"[2] In Astounding Science Fiction magazine, P. Schuyler Miller gave the collection a somewhat mixed review, saying that "Bond lacks few of the tricks of the born storyteller, and uses them all blandly and shamelessly.
