Dollendorf was first referred to in a 966 document by Emperor Otto I, and an 1144 deed first made the distinction between Oberdollendorf and Niederdollendorf. From the 15th century onwards Oberdollendorf was part of the Duchy of Berg in its administrative unit of Löwenburg. In 1597 Oberdollendorf was part of the "Linz Concord", a mutual defence treaty between cities along the Rhine. The parishes of Niederdollendorf, Oberdollendorf and Oberkassel together formed the court system of Dollendorf. The parish Oberdollendorf was up to the dissolution of the Duchy of Berg in 1806 administered through a "Markgedinge", to which the seven commons of the village seconded jurors: the Grevenhof of Heisterbach Abbey, the Mertenhof of the Merten Priory, the estates of the lords of Drachenfels, the Rennenbergerhof of the lords of Rennenberg, the Edelkirchenerhof of the lords of Edelkirchen in Römlinghoven and the "Klamerspol" of the Junkers zu Kalmit. The parish had following officers: a mayor, a parish administrator, a sacristan and a gendarm. They were appointed by the "Markgedinge" and -with the exception of the sacristan- regularly replaced. From 1816 to 1969 the municipality of Oberdollendorf was part of the mayoralty of Oberkassel, within Prussia's Rhine Province. From 1949 to 1955 the town formed part of the "Enklave Bonn", a special administrative area set up around the provisional seat of government of the Federal Republic of Germany under the command of the Allied High Commission. As part of the municipal reorganization of Bonn in 1969 the town was assigned to the city of Königswinter.

Economy
Until well into the 19th century the economic activity in Oberdollendorf was dominated by wine production. In 1878, 51.06 hectares were under cultivation, which dropped to 23 hectares in 1906 and 5.5 hectares in 1924. Following the Great Depression job creation programs encouraged re-cultivation and the area again rose to 23 hectares in 1934. By 1939 Oberdollendorf counted 89 wineries, although most of them were only operated as a sideline to another business. Today there is only one winery left. The vineyards on the western slope of the "Dollendorfer Hardt" are classified as part of the Mittelrhein wine growing region, Siebengebirge wine district, Petersberg site and from north to south include the vineyards of Rosenhügel, Laurentiusberg and Sülzenberg.
