Fritz David Carlson (July 23, 1888 – November 28, 1952) was a Swedish mathematician. After the death of Torsten Carleman, he headed the Mittag-Leffler Institute.

Carlson's contributions to analysis include Carlson's theorem, the Polyá–Carlson theorem on rational functions, and Carlson's inequality

$\left( \sum_{n=1}^\infty |a_n|\right)^4 \leq \pi^2 \sum_{n=1}^\infty |a_n|^2 \, \sum_{n=1}^\infty n^2 |a_n|^2~.$

In number theory, his results include Carlson's theorem on Dirichlet series.

Hans Rådström, Germund Dahlquist, and Tord Ganelius were among his students.
