The Christian Democratic Union (lt|Krikščionių demokratų sajunga, KDS) was a political party in Lithuania.
The party was established as the Lithuanian Christian Democratic Union (LKDS). It contested the 1992 elections in an alliance with Young Lithuania, with the alliance winning a single seat, taken by the LKDS.[1] The party won only a single seat in the 1996 elections, and changed its name to "Christian Democratic Union" in the same year.[2] The 2000 elections saw the party retain its single seat, increasing its vote share from 3% to 4%.
In 2001 it merged with the Lithuanian Christian Democratic Party to form the Lithuanian Christian Democrats.[2]
