Radelfingen is a municipality in the Seeland administrative district in the canton of Bern in Switzerland.

Radelfingen is first mentioned in 894 as Ratolingun in a donation made by Pirins to the Abbey of St. Gall.

During the Middle Ages, the nearby Kyburg herrschaft of Oltigen and the Counts of Thierstein owned land in Radelfingen.

The right to hold the low court was owned by local nobles until 1502 when Frienisberg Abbey acquired the right and gave it over to Bern.

In 1906, the first Postauto in Switzerland, began service between Bern and Detligen with a stop in Radelfingen.

During the early 20th century, the population of the villages declined as increasingly mechanized agriculture required fewer workers.

However, by the 1980s, the population stabilized in Radelfingen and agriculture remained important to the local economy.

[5] The municipality is located on the right bank of the Aare reservoir and on the edge of the Frienisberg Plateau.

It consists of the villages of Radelfingen and Detligen along with the hamlets of Landerswil, Ostermanigen, Jucher, Matzwil, Oltigen and Oberruntigen as well as scattered individual farm houses.

The blazon of the municipal coat of arms is Argent a Wheel Gules.
