The Volkswagen Polo GTI R5 is a rally car built by Volkswagen Motorsport and based upon the Volkswagen Polo road car. It is built to R5 regulations and is a successor to the Volkswagen Polo R WRC. The Polo GTI R5 made its competitive début at the 2018 Rally Catalunya, where it was driven by 2003 World Drivers' Champion Petter Solberg and Eric Camilli. The car currently competes in the World Rally Championship-2 where it is entered by various privateers.

In international rallying, R5 refers to a class of cars competing under Group R regulations. R5 regulations were introduced by the Fédération Internationale de l'Automobile (FIA) in 2012 as a replacement for the Super 2000 class. In 2019 the FIA renamed the R5 specification ruleset to Group Rally2 as part of a wider plan to reorganise FIA championships and replace Group R with new Groups Rally. Existing FIA homologated R5 cars remain eligible for any FIA Rally2 level competition, and non-homologated R5 or Rally2 cars should be accepted equally at national level where approved. R5/Rally2 cars are based on production cars and feature a 1600cc turbocharged petrol engine.
