Abstract
We determine the three-loop quartic -function for the most general renormalisable four-dimensional theories. A general parametrization of the -function is compared to known -functions for specific theories to fix all coefficients. Three-loop -functions for the cubic coupling and scalar mass terms also follow from the result, which is made available in software packages.
