The Kardinal-Frings-Gymnasium (KFG, until 1979 Erzbischöfliches Gymnasium Beuel) is a private catholic secondary school of the Roman Catholic Archdiocese of Cologne in Beuel, a borough of the former German capital Bonn in North Rhine-Westphalia.

The school was founded in 1964 as Erzbischöfliches Gymnasium Beuel (EBG) by the Archbishop of Cologne, Josef Kardinal Frings. It was a boys´ school. The school building in the south of Beuel, which includes an assembly hall, a sports field, three sports halls, a cafeteria and a nuclear bunker was planned by the famous architect Joachim Schürmann. After Frings' death in 1978, the school decided to assume the name of its founder and was officially named as Kardinal-Frings-Gymnasium on December 8, 1979. In 1988, the school was opened for girls.

The school is known for its brass orchestra. The popular German brass band Querbeat, which is active in the Cologne Carnival, was founded in 2001 as a school band of the Kardinal-Frings-Gymnasium.
In 2001, the school initiated the Social Project Armenia. At an annual run the students collect money, which is used for an exchange program, the support of German lessons at two partner schools in Gyumri and the renovating of village schools in the north-Armenian Region Shirak. The donation volume in the last 15 years is more than 250.000 Euros (December 2017).

On July 3, 2018, the KFG hosted a ten-minute live switch to the German ESA-astronaut Alexander Gerst, who answered the students' questions from the International Space Station ISS via amateur radio. The contact was part of the ARISS project and was carried out by the German Amateur Radio Club and the German Aerospace Center. Guests included the former astronaut Reinhold Ewald.
