A life form or lifeform is an entity or being that is living or alive.[1][2] This is a list of articles that relate to physical, hypothetical, alleged, religious, or fictional life forms.

More than 99 percent of all species, amounting to over five billion species,[3] that ever lived on Earth are estimated to be extinct.[4][5] Estimates on the number of Earth's current species range from 10 million to 14 million,[6] of which about 1.2 million have been documented and over 86 percent have not yet been described.[7]

In process philosophy, objects in the world or universe are layered or tiered in complexity.[8] Living things are difficult to define,[9] but life forms can be considered to be the most complex entities in the arena or environment in which they exist.[10] As in process philosophy, this article brings together in a holistic manner, life forms from the diverse human intuitions found in experiences that include the ethical, religious, philosophical, scientific, and aesthetic.[11]
