Death Penalty in Missouri

As of October 2026, Missouri remains one of the 27 U.S. states that retain the death penalty in law. Missouri law authorizes lethal injection or lethal gas.

Current legal status

The death penalty remains part of Missouri law. That does not necessarily mean executions occur regularly: capital punishment in the United States varies sharply by state because death sentences, appeals, clemency, execution warrants, drug availability, court orders and executive policy can all affect whether a sentence is carried out.

This state page is therefore linked to the broader Execution Methods in the United States archive rather than repeating technical protocol details that can change over time.
