In mathematics, a protorus is a compact connected abelian topological group. Equivalently, it is a projective limit of tori (products of a finite number of copies of the circle group), or the Pontryagin dual of a discrete torsion-free abelian group.

Some examples of protori are given by solenoid groups.
