Voters passed Amendment 3 to enshrine reproductive health care rights, including the right to abortion and birth control, in the Missouri Constitution, reversing the state’s near-total ban on abortion implemented after Roe v. Wade was overturned in 2022.

Abortion rights advocates prevailed on seven ballot measures across the U.S. in Tuesday's election and lost on three.The losses are the first on statewide reproductive rights ballot measures anywhere in the U.

Missouri’s current law bans abortion with almost no exceptions and this amendment would allow abortion to about 24 weeks of pregnancy.
