图厄（挪威语：Axel Thue，1863年2月19日－1922年3月7日），挪威数学家，以丢番图逼近与组合数学方面的贡献而闻名。他在1914年发表了词法问题或图厄问题，这和停机问题密切相关。

Axel Thue (Norwegian: [tʉː]; 19 February 1863 – 7 March 1922), was a Norwegian mathematician, known for highly original work in diophantine approximation, and combinatorics.

He stated in 1914 the so-called word problem for semigroups or Thue problem, closely related to the halting problem.
