L. Håkan Eliasson (born 13 July 1952) is a Swedish mathematician.

Eliasson received in 1984 his PhD from the under Jürgen Moser with thesis Hamiltonian systems with Poisson commuting integrals. He was a professor at the Royal Institute of Technology in Stockholm and then became a professor at the University of Paris VII (Denis Diderot) and the Institut de mathématiques de Jussieu of the Universities Paris VI and VII and the CNRS.

His research deals with dynamical systems, quasiperiodic motion, the problem of small denominators in perturbation theory, the KAM Theory and multiscale analysis in perturbation theory, Hamiltonian partial differential equations, and localization and diffusion in quasiperiodic Schrödinger operators.

In 1998 he was an Invited Speaker at the International Congress of Mathematicians in Berlin. In 2005 and in 2012 he was at the Institute for Advanced Study.

In 1995 he received the Salem Prize and 2008 he received the Sophie Germain Prize.
