Turnu Măgurele (Romanian pronunciation: [ˌturnu məɡuˈrele]) is a city in Teleorman County, Romania, in the historical region of Muntenia.

Developed nearby the site once occupied by the medieval port of Turnu, it is situated north-east of the confluence between the Olt River and the Danube, at the edge of the Wallachian Plain.

The first documentary attestation of the town appears in a diploma issued by Sigismund of Luxembourg, king of Hungary, on the occasion of the battles fought here in 1394.

After the 1989 Revolution, the municipality suffered a sharp decline as a result of the collapse of industrial and economic activities and the migration of the population to the larger cities as well as to other European states.

What is certain is that during the reign of Mircea the Elder, this settlement played an important role in the defensive strategy of Wallachia in the face of the Ottoman danger.

The document describes the context and history of Sigsmund's struggles in support of Mircea the Elder, his vassal, to return to the throne of Wallachia.

The Ottomans ruled Turnu (Kule in Turkish, Holavnik in Bulgarian) with some intermittencies (between 1462, 1594–1600, and 1772–1774), during the anti-Ottoman rebellions of Vlad III the Impaler and Michael the Brave, until 1826, when it was ceded to Wallachia through the 1826 Akkerman Convention, along with Giurgiu and Brăila.

A chemical and textile industry center in the past, the city has more recently been diversifying its economy, with enterprises such as ElectroTurris (an electrical engine factory), and ConservTurris (a food processing plant).
