The Party of Common Sense (Czech: Strana zdravého rozumu) is a Czech nationalist political party,^[6] led by Petr Hannig.

The party was founded in 2002 by Petr Hannig. The party received 0.2% of the vote in the 2002 Czech parliamentary election and failed to reach the 5% threshold for representation.^[7] This increased to 0.5% of the vote in the 2006 election.

In 2009, the party began collaborating with former Eurosceptic MEP Jana Bobošíková and other independent candidates. This electoral alliance ran in the 2009 European election under the name 'Sovereignty', led by Bobošíková. The list came fifth, winning 4.3% of the vote, just short of the 5% threshold for representation.

In 2010, the party changed its name to Sovereignty – Party of Common Sense (Suverenita – Strana zdravého rozumu), and won 3.7% in the 2010 election, again falling short of parliamentary representation. The cooperation between the two parties subsequently ended,^[8] and the party returned to its original name in 2014.
