The United Democratic Christians (Democratici Cristiani Uniti, DCU) was a tiny Christian-democratic Italian political party based in the Italian region of Apulia.
The party was founded by Giovanni Mongiello, formerly a Christian Democrat, who had been Under-Secretary of Agriculture in the second Prodi government, by a split from the Union of Christian and Centre Democrats (UDC) in 2004. Mongiello and his followers were mostly former members of the United Christian Democrats, who had opposed the merger into of their party into the new grouping. Mongiello had been President of the Party of Christian Democracy until 2005, before launching his own party.
In the 2006 general election the party was affiliated to The Union, the centre-left coalition led by Romano Prodi.
