The United Democrats - Association of Independents (Czech: Spojení demokraté - Sdružení nezávislých, SD-SN) is a small Czech extra-parliamentary political party, formed from what remained of the European Democrats (Czech: Evropští demokraté) after that party's merger in 2006 with SNK Union of Independents to form SNK European Democrats.

From 2004, this party began cooperating with the SNK Union of Independents, winning 11% of the vote in the 2004 European Parliament election.

In January 2006, the European Democrats agreed on a merger with SNK Union of Independents, to become SNK European Democrats; most of the party members left to join the new party.

[2] However, the original party was not dissolved due to an ongoing judicial dispute regarding the 2002 local elections in Prague.

Its nominee Ondřej Dostál, a lawyer and former health expert for the Czech Pirate Party, was second on the list, and was elected as an MEP.
