Centrists of Catalonia (, , CC–UCD) was a Catalan-based electoral alliance formed in June 1978 ahead of the upcoming local and general elections, comprising the Catalan section of the Union of the Democratic Centre (UCD), the Union of the Centre of Catalonia (UCC) and the Democratic Union–Broad Centre (UDCA). The alliance was maintained after the election, with UCD and UDCA agreeing to transform it into a full-fledged political party in December 1979 with the disagreement of the UCC, which chose not to join the new party.

On the one hand, the Catalan Centre started negotiations with the UCD Catalan branch and other political parties throughout the second half of 1977, leading to the establishment of the Union of the Centre of Catalonia (UCC) in March 1978, with which the UCD would first sign an electoral agreement for the local elections, then establish a common platform in June that year—often referred to as a "liaison political committee"—to oversee a future merger between both parties. This course of action was initially met with skepticism within several UCD sectors, with some remaining reluctant of negotiating under equal conditions with political groups failing to garner any electoral successes, and some others—such as Adolfo Suárez himself—being weary of consenting to a
