Groß Ippener is a municipality in the district of Oldenburg in Lower Saxony, Germany.

In 1211 the term Ippener was first mentioned in a certificate of the Bassum abbey, in which the noble Aldagus de Ippenerde is listed as a witness.

There, the clerics of the Bremen monastery confirm the possession of the tithes of "Ippenerthe" to the abbey of Bassum, that was gifted them by the Abbess Elisabeth.

The rural community of the newly formed municipality had a total of 64 houses with 440 residents.

The council elected alderman George Drube (CDU) as honorary mayor for the current legislature term.
