The Primvs derby, also known as The Only Derby (Romanian: Unicul derbi), is a Romanian football derby contested between Liga I clubs Rapid București and Petrolul Ploiești. The name derives from the rivalry's status as one of the earliest in Romanian football, dating back to the interwar period, when both clubs were based in Bucharest and emerged as leading competitive sides in the country.

The rivalry is usually contested at least twice per season in league competition, and also extends to matches in the Cupa României. Throughout their histories, the two clubs have alternated between periods of success and decline, competing for domestic honors during their peak years and experiencing setbacks such as bankruptcy or relegation to the second division.

At various times, the clubs have also faced each other in promotion battles to return to the top flight, seeking to re-establish their status among Romania's leading teams.
