The Dominican Liberation Party is a political party in the Dominican Republic. Founded in 1973 by former president Juan Bosch, the party, along with the Dominican Revolutionary Party, and Social Christian Reformist Party, has dominated politics in the country since the establishment of democracy in the early 1960s.

Juan Emilio Bosch y Gaviño was a Dominican politician, historian, writer, essayist, educator, and the first democratically elected president of the Dominican Republic for a brief time in 1963. Previously, he had been the leader of the Dominican opposition in exile to the dictatorial regime of Rafael Trujillo for over 25 years. To this day, he is remembered as an honest politician and regarded as one of the most prominent writers in Dominican literature. He founded both the Dominican Revolutionary Party (PRD) in 1939 and the Dominican Liberation Party (PLD) in 1973.
