In algebraic K-theory, a field of mathematics, the Steinberg group $\operatorname{St}(A)$ of a ring $A$ is the universal central extension of the commutator subgroup of the stable general linear group of $A$ .

It is named after Robert Steinberg, and it is connected with lower $K$ -groups, notably $K_{2}$ and $K_{3}$ .
