Stevo Todorčević FRSC (Serbian Cyrillic: Стево Тодорчевић; born February 9, 1955), is a Yugoslavian mathematician specializing in mathematical logic and set theory.

[4] At Belgrade University, he studied pure mathematics, attending lectures by Đuro Kurepa.

In Todorčević's 1978 master’s thesis, he constructed a model of MA + ¬wKH in a way to allow him to make the continuum any regular cardinal, and so derived a variety of topological consequences.

Here MA is an abbreviation for Martin's axiom and wKH stands for the weak Kurepa Hypothesis.

[13] Todorčević has been described as "the greatest Serbian mathematician" since the time of Mihailo Petrović Alas.
