The works of the 17th-century mathematician [[Pierre de Fermat]] engendered many [[theorem]]s. '''Fermat's theorem''' may refer to one of the following theorems:

* [[Fermat's Last Theorem]], about integer solutions to ''a''<sup>''n''</sup>&nbsp;+&nbsp;''b''<sup>''n''</sup>&nbsp;=&nbsp;''c''<sup>''n''</sup>
* [[Fermat's little theorem]], a property of prime numbers
* [[Fermat's theorem on sums of two squares]], about primes expressible as a sum of squares
* [[Fermat's theorem (stationary points)]], about local maxima and minima of differentiable functions
* [[Fermat's principle]], about the path taken by a ray of light
* [[Fermat polygonal number theorem]], about expressing integers as a sum of polygonal numbers
* [[Fermat's right triangle theorem]], about squares not being expressible as the difference of two fourth powers
