Die gelykteken of gelykaanteken (=) is 'n wiskundige simbool wat gebruik word om gelykheid aan te dui. Dit is in 1557 deur Robert Recorde geskep.[1] In 'n vergelyking word die gelykteken tussen twee (of meer) uitdrukkings met dieselfde waarde geplaas. In Unicode en ASCII word die gelykteken geënkodeer met U+003D.
