This page lists state ballot measures in the United States in 1968 in the United States by state. Measures are included whether they are initiated by a state legislature or by the citizens of said state. Subheadings are included under a state if there was a measure that was held on a different date with the subheading being the date of the ballot measures. Results for each measure are included the "Results" heading and not under headings for each state with only whether they passed or not being included.

These measures were held during a time when traction was being gained to reduce the voting age due to the ongoing Vietnam War and for more civil rights during the conccurent civil rights movement such as a veto referendum which if passed would have banned housing discrimination in Maryland (this measure did not pass) and a measure in Washington which passed that allowed for revocation or suspension of one's real estate license if one discriminated based on a person's race or origin. One example of a referendum to lower the voting age was in Hawaii where it proposed to lower it from 20 to 18 but this measure failed.

Wyoming established a process for citizens to initiate amendments, laws or have a veto with Amendment 2.
