General elections were held in Luxembourg on 15 December 1968. The Christian Social People's Party (CSV) remained the largest party, winning 21 of the 56 seats in the Chamber of Deputies.
In the aftermath of the election, the CSV dropped their previous coalition partners, the Luxembourg Socialist Workers' Party, and formed a new government with the Democratic Party. This led to the creation of the second Werner-Schaus government.
a The percentage of votes is not related to the number of votes in the table, as voters could cast more votes in some constituencies than others, and is instead calculated based on the proportion of votes received in each constituency.
