Soylent is a set of meal replacement products in powder, shake, and bar forms, produced by Soylent Nutrition, Inc. The company was founded in 2013 and is headquartered in Los Angeles, California.

Soylent is named after an industrially produced food (the name of which is a portmanteau of "soy" and "lentil") in Make Room! Make Room!, a 1966 dystopian science fiction novel (which was the basis of the 1973 film Soylent Green) that explores the theme of resource shortages in the context of overpopulation.

The company developed a following initially in Silicon Valley and received early financial backing from GV, the investment arm of Alphabet, Inc., and venture capital firm Andreessen Horowitz. In 2021, Soylent announced that it had become profitable starting in 2020.
