MPs with the Left group announced their initiative on Monday and asked for a meeting with the lower-house Speaker to ensure swift processing of the draft legislation, Polish state news agency PAP reported.
Poland's new parliament convened for its first session on Monday, following last month's parliamentary election.
MPs told reporters that the Left group had drafted bills to legalise abortion up to 12 weeks of pregnancy and to decriminalise abortion.
Lawmaker Katarzyna Kotula said the group would seek a meeting with the newly elected Speaker, Szymon Hołownia, "to ensure that these abortion bills are processed."
She told PAP she was confident that "the bill to decriminalise abortion can gain the support of a majority of lawmakers."
Kotula noted that her group had pledged to relax Poland's abortion regulations during the election campaign, adding that "this pledge must be fulfilled."
Abortion is allowed in Poland only when the pregnancy poses a threat to the "life or health" of the woman, or in cases of a "forbidden act," such as rape or incest
The country's abortion regulations were last modified after its Constitutional Tribunal in October 2020 ruled that abortion due to serious fetal defects and severe illnesses was unconstitutional.
The ruling prompted a wave of protests across the country.
Poles elected a new set of 460 MPs and 100 senators when they went to the ballot box last month.
Polish President Andrzej Duda on Monday named outgoing Prime Minister Mateusz Morawiecki as prime minister-designate, tasking him with forming a new Cabinet.
Morawiecki's conservative Law and Justice (PiS) party won Poland's October 15 election, but lost its parliamentary majority and looks unlikely to stay in power for a third consecutive term.
A bloc of pro-EU opposition parties, including the Left, on Monday secured a resounding victory in Poland's new parliament during its first key vote to elect a house Speaker.
Poland's pro-European opposition groups on Friday signed an agreement to form a coalition government, pledging to restore the rule of law, promote green energy and relax abortion rules, among other policies.
