Gábor Tardos (born 11 July 1964) is a Hungarianmathematician, currently a professor and Canada Research Chair at Simon Fraser University. He works mainly in combinatorics and computer science. He is the younger brother of Éva Tardos.

Tardos started with a result in universal algebra: he exhibited a maximal clone of monotone operations which is not finitely generated. He obtained partial results concerning the Hanna Neumann conjecture. With his student, Adam Marcus, he proved a combinatorial conjecture of Zoltán Füredi and Péter Hajnal which was known to imply the Stanley–Wilf conjecture. With topological methods he proved that if ${\displaystyle {\mathcal {H}}}$ is a finite set system consisting of the unions of intervals on two disjoint lines, then ${\displaystyle \tau ({\mathcal {H}})\leq 2\nu ({\mathcal {H}})}$ holds, where ${\displaystyle \tau ({\mathcal {H}})}$ is the least number of points covering all elements of ${\displaystyle {\mathcal {H}}}$ and ${\displaystyle \nu ({\mathcal {H}})}$ is the size of the largest disjoint subsystem of ${\displaystyle {\mathcal {H}}}$. Tardos worked out a method for optimal probabilistic fingerprint codes. Although the mathematical content is hard, the algorithm is easy to implement.
