The Slovak Democratic and Christian Union – Democratic Party (Slovak: Slovenská demokratická a kresťanská únia – Demokratická strana, SDKÚ-DS) is a christian - democratic political party in Slovakia. Before its merger with the Democratic Party on January 21, 2006, it was called the Slovak Democratic and Christian Union (SDKÚ).
It used to provide Slovakia's head of government, Mikuláš Dzurinda, and led a coalition government with the Party of the Hungarian Coalition in the years 2002-2006 (the Alliance of the New Citizen was a member of that coalition until September 2005 and the Christian Democratic Movement until February 2006).
In the parliamentary election of 17 June 2006, the party won 18.4% of the popular vote and 31 out of 150 seats.
As of February 2008, the party is struggling with ever decreasing party polls. Juraj Liška, one of the party's deputy leaders, asked Dzurinda to resign as the party leader.
SDKÚ-DS is a member of the European People's Party (EPP).
