Ostwestfalen-Lippe ([ˌɔstvɛstfaːlənˈlɪpə] , literally East(ern) Westphalia-Lippe, abbreviation OWL) is the eastern region of the German state of North Rhine-Westphalia, congruent with the administrative region of Detmold and containing the eastern part of Westphalia, joined with the Lippe region. The region has a population of about two million inhabitants. The major cities are Bielefeld, Paderborn, Gütersloh, Minden, Detmold, and Herford. The highest hill of Ostwestfalen-Lippe is the Totenkopf (498 m). Some major globally operating companies are headquartered in the region, for example Bertelsmann, Miele, Dr. Oetker, Melitta, Gerry Weber, DMG Mori Aktiengesellschaft, Hörmann, Schüco, Wincor Nixdorf, Phoenix Contact, HEGLA and Claas. In 2012 OWL became Germans BMBF Leading Edge Technology Cluster for intelligent Technical Systems (it's OWL ), which is currently the largest public funded project in the context of the government initiative "Industry 4.0". Universities are located in Bielefeld, Paderborn and Lemgo. The Fraunhofer Society is engaged in OWL in Lemgo and Paderborn. The Teutoburg Forest stretches across the region. It is the supposed site of the Battle of the Teutoburg Forest in the year 9 AD, where an alliance of Germanic tribes defeated a Roman army. In 1875, a statue was unveiled of the commander Arminius, who led the Germanics to victory at the battle. This statue, the Hermannsdenkmal, is one of the best-known sights in Ostwestfalen-Lippe.

The County of Lippe (German: Grafschaft Lippe) or Lippe-Detmold was an Imperial Estate of the Holy Roman Empire. It had its origins in a small lordship on the Lippe river, first attested in 1123, and lands leased from the Bishopric of Paderborn from 1173. In the late twelfth and early thirteenth centuries, the lords of Lippe founded several cities (Lippstadt, Lemgo, Horn, Blomberg, and Detmold), the earliest city-foundations in Westphalia. The territory achieved Imperial immediacy in 1413 at the latest and was part of the Lower Rhenish–Westphalian Circle from 1512. In 1528 or 1529, it was promoted to the status of Imperial County and became part of the College of Lower Rhenish-Westphalian Imperial Counts in the Imperial Diet. Lippe was a centre of conflict during the Reformation as Count Simon V attempted to prevent Protestantism from spreading within his territory by force. Lutheranism was adopted in 1538, two years after his death. Simon VI converted to Calvinism in 1605, leading to a prolonged conflict with Lemgo, which eventually remained Lutheran. On his death in 1613, Simon VI left substantial lands and rights to his younger sons, who formed junior lines: Lippe-Brake and Lippe-Alverissen (which inherited Schaumburg-Lippe in 1644), while the main line became known as Lippe-Detmold. The Counts' efforts to centralise the state and expand its military and bureaucracy in the eighteenth century were stymied by the power of the junior lines and the nobility. In 1789 it became the Principality of Lippe.

The Free State of Lippe (German: Freistaat Lippe) was created following the abdication of Prince Leopold IV of the Principality of Lippe on 15 November 1918, following the German Revolution. It was a state in Germany during the Weimar Republic and Nazi Germany. After the end of the Second World War, the Control Commission for Germany – British Element (CCG/BE) abolished the state of Lippe in January 1947 and incorporated it into the new German state of North Rhine-Westphalia that had been created three months earlier.

Today it is the administrative center of the district of Lippe and of the Regierungsbezirk Detmold. The Church of Lippe has its central administration located in Detmold.
