In a statement, Denkov described his resignation as an "invitation to negotiations" with the coalition partner, the Citizens for European Development of Bulgaria (GERB) party.
"My resignation is not a political game but the result of a promise made before,'' he said.
He added that his government will continue its duties until the next government is formed.
According to an agreement between the GERB party and a bloc led by Denkov’s We Continue to Change party, his nine-month term expires on March 6.
Foreign Minister Maria Gabriel, who represents the GERB party, will take over as prime minister.
Denkov became prime minister following a vote of confidence from parliament on June 6 last year.
His resignation must be approved by parliament.
