The GR footpaths are a network of long-distance walking trails in Europe, mostly in France, Belgium, the Netherlands, and Spain.

They go by the following names: French: sentier de grande randonnée, West Flemish: Groteroutepad, Dutch: Langeafstandwandelpad, Spanish: sendero de gran recorrido, Portuguese: percurso pedestre de grande rota – generally meaning "long trail" or more literally "great route".

The GR trails are marked using a system of blazes that are visible in both directions: Red and white was chosen as the most visible colour combination in natural surroundings.

Waymarks are often painted, but may take the form of metal signs in city centers.

Since 2017 the French Hiking Federation has allowed people to vote for the GR Préféré des Français award that goes to peoples favourite trails, for following year.
