Titisee-Neustadt (German: [ˌtɪtizeːˈnɔʏʃtat] ⓘ) is a municipality in the district of Breisgau-Hochschwarzwald in Baden-Württemberg in southern Germany.

The town lies on a small river called the Seebach (Lake Brook) as it comes in from Feldberg-Bärental to feed Titisee, as the Gutach (Good Water) as it flows out of the lake, and east of Neustadt, where it merges with the Haslach to become a whitewater torrent, as the Wutach (Furious Water).

After flowing out of the town, it passes through the well known Wutachschlucht (Wutach Gorge), and ends by emptying into the Rhine.

Titisee-Neustadt is divided into six communities (Neustadt, Langenordnach, Rudenberg, Schwärzenbach, Titisee, Waldau) which historically have been separate, although they are now amalgamated into one municipality.

This he managed to do through a loan of, all together, 700,000 Reichsmark, which he obtained through negotiations with major banks in the United States, Switzerland and the Netherlands.

Through further job-making measures, such as public building schemes, about the time of the Great Depression, he was in a position to keep the jobless rate in Neustadt at a comparatively low 12%, whereas it was then 18% in Germany as a whole.

Later came the Nazi régime, which used Der Hochwächter and the Echo vom Hochfirst, the local newspapers, for their own ends, later shutting them both down.

Despite exerting this influence, the Party's share of the vote in Neustadt was always lower than in Titisee, where it compared with the national average.

Blasius Müßle, who became mayor at that time, was replaced in 1935 by the later Kreisleiter (District Leader) Benedikt Kuner.

Titisee-Neustadt came into being in 1971 with the amalgamation of the until then independent district capital of Neustadt with the communities of Titisee and Rudenberg.

Due to Covid-19, the 2020–21 FIS Ski Jump World Cup in Titisee-Neustadt will take place without visitors.

Buses cover areas not served by trains, for instance Titisee to Lenzkirch and Todtnau.
