The Democratic Party of South Tyrol (, DPS) was a minor regionalist liberal, green and social-democratic political party active in South Tyrol, Italy. It was a left-wing alternative to the dominant South Tyrolean People's Party.
The party was founded in 1997, as a continuation of the Social Democratic Party of South Tyrol, and was led by Roland Girardi.
In the 1998 provincial election the DPS formed a joint list with the Ladins Political Movement, while five years later it supported the Greens.
In 2008 most Democrats joined the Greens.
