Kirill Kavokin (born 26 November 1962 in Leningrad) is a Russian physicist working on solid state physics, semiconductor optics and spin physics.

He also works on animal vision and magnetoreception.

He is currently leading scientist at the Spin Optics Laboratory (SOLAB) at Saint-Petersburg State University (SPbSU) and at the I. M. Sechenov Institute of Evolutionary Physiology and Biochemistry, in Saint Petersburg, Russia.

He is the author or co-author of over 200 peer-reviewed publications, with key works on spin relaxation in semiconductors, which he studies at both a theoretical and experimental level.

He also applied his knowledge of magnetic phenomena in solids to the problem of animal magnetoreception, in particular of garden warblers.
