Sverker Johansson is a Swedish physicist, linguist, textbook author and university professor.

He created Lsjbot, a Wikipedia bot.

He received his doctorate in physics in 1990 on a thesis in particle physics on μμ and eμ pair production at the experiment HELIOS at the collider SPS and software development for the experiment DELPHI at the collider LEP, both experiments at CERN.

He has subsequently worked as a researcher in several fields, mainly neutrino-related particle physics with the AMANDA experiment but also in the origin of language.

Johansson's book Origins of Language, Constraints of Hypotheses, and Convergence Evidence in Language and Communication Studies, published in 2005, has been reviewed by the Journal of Linguistics.
