Abortion in Missouri is legal up to the point of fetal viability as a result of 2024 Missouri Amendment 3, which took effect in December 2024 after narrowly passing in the November 5 general election. Legal challenges to allow access are ongoing, and clinics were able to open on February 15, 2025.

At least one clinic in Kansas City and St. Louis is providing abortions. A clinic in Columbia opened up in March 2025.

In 2014, a poll by the Pew Research Center found that 45% of Missouri adults said that abortion should be legal vs. 50% that believe it should be illegal in all or most cases and 5% that do not know. The 2023 American Values Atlas reported that, in their most recent survey, 55% of Missourians said that abortion should be legal in all or most cases.
