In the United States, a utilities commission, utility regulatory commission (URC), public utilities commission (PUC), or public service commission (PSC) is a governing body that regulates the rates and services of a public utility, such as an electric utility. In some cases, government bodies with the title "public service commission" may be civil service oversight bodies, rather than utilities regulators.

In Canada, a public utilities commission (PUC) is a public utility owned and operated by a municipal or local government under the oversight of one or more elected commissioners. It is not a regulatory body. Its role is analogous to a municipal utility district or public utility district in the US.
