Xero is a company in Grand Theft Auto IV presumably specialized in petroleum. Unlike its competitors, Xero does not appear to have set up any gas stations in Liberty City, although it does operate a refinery at the southwestern corner of the Acter Industrial Park in Alderney. Xero storage tanks and faded advertising of the brand can also be found in selected parts of the city, and Xero sponsorship vinyls are visible on certain Bati Customs designs. Xero is a BAWSAQ-listed company.

Its name and logo design appear to be similar to that of Xoomer in Grand Theft Auto: San Andreas.
