Kalevi Kull (born 12 August 1952, Tartu) is a biosemiotics professor at the University of Tartu, Estonia.
He graduated from the University of Tartu in 1975. His earlier work dealt with ethology and field ecology. He has studied the mechanisms of species coexistence in species-rich communities and developed mathematical modelling in ecophysiology. Since 1975, he has been the main organiser of annual meetings of theoretical biology in Estonia. In 1992, he became a Professor of Ecophysiology in the University of Tartu. In 1997, he joined the Department of Semiotics, and became a Professor in Biosemiotics. From 2006 to 2018, he was the Head of the Department of Semiotics in the University of Tartu, Estonia. His field of interests include biosemiotics, ecosemiotics, general semiotics, theoretical biology, theory of evolution, history and philosophy of semiotics and life science.
He was the president of the Estonian Naturalists' Society in 1991–1994. He is a founder of the Jakob von Uexküll Centre. He is the president of the International Society for Biosemiotic Studies since 2015.
Ecologist Olevi Kull was his younger brother.

Important concepts
-
Biosemiotic concept of species. A species concept based on recognition window of organisms, which is responsible for intraspecific variability range and the minimum width of hiatus.
[Kull, Kalevi 1993. Recognition concept of species and a mechanism of speciation. Folia Baeriana 6. Tartu, 133–140.][Kull, Kalevi 2016. The biosemiotic concept of the species. Biosemiotics 9(1): 61–71.]
-
Recognition window. The range of mediated fitting (semiotic fitting), as based on the scope of indistinguishability.
[Kull, Kalevi 2018. On the logic of animal umwelten: The animal subjective present and zoosemiotics of choice and learning. In: Marrone, Gianfranco; Mangano, Dario (eds.), Semiotics of Animals in Culture: Zoosemiotics 2.0. (Biosemiotics 17.) Cham: Springer, 135–148.]
-
Semiotic fitting. The agent’s capacity for making and preserving the local semiotic bonds, meaning the agent’s functional or communicational match with its surrounding.
[Kull, Kalevi 2020. Semiotic fitting and the nativeness of community. Biosemiotics 13(1): 9–19.]
-
Emon. A type of sign that is based on imitation (as different from symbol which is based on convention, or index which is based on association, or icon which is based on indistinguishability).
[Kull, Kalevi 2019. Steps towards the natural meronomy and taxonomy of semiosis: Emon between index and symbol? Sign Systems Studies 47(1/2): 88–104.]
-
Umweb. Non-momentary or diachronic or distributed umwelt.

Eponymous species
In 2021, a Costa Rican
Braconidae species new to science,
Hymenochaonia kalevikulli Sharkey & van Achterberg, was named for Dr. Kull.
