The Democratic Social Christian Party (; PSDC) is a political party in Democratic Republic of the Congo.
The PSDC was formed in April 1990 by Joseph Ileo following a speech by Mobutu Sese Seko announcing the end of the single-party rule, taking on a social-democratic platform that emphasised morality and Christian values.
Following the death of Ileo in September 1994, André Bo-Boliko Lokonga assumed presidency of the PSDC, and was approved to the post in September 1995 during the party's national convention.
