Bielefeld – Gütersloh II is an electoral constituency (German: Wahlkreis) represented in the Bundestag.

It is located in eastern North Rhine-Westphalia, comprising the city of Bielefeld and a small part of the district of Gütersloh.

As of the 2021 federal election, it comprises the independent city of Bielefeld and the municipality of Werther from the Gütersloh district.

In the 1976 election, it was coterminous with Bielefeld excluding the former municipalities of Brackwede, Sennestadt, Senne, Gadderbaum, and Schröttinghausen.

The constituency has been held by the Social Democratic Party (SPD) during all but two Bundestag terms since 1949.

It was first represented by Friederike Nadig of the SPD from 1949 to 1953, followed by Artur Ladebeck and Otto Walpert for a single term each.

Kurt Vogelsang then served a single term before Reinhard Meyer zu Bentrup of the Christian Democratic Union (CDU) was elected.

Rainer Wend served from then to 2009, when Christina Kampmann of the CDU won the constituency.
