William Faust (March 29, 1929 – January 21, 1995) was a Democratic member of the Michigan Senate from 1967 through 1994, and was majority leader from 1976 to 1984.

[2] In 1966, Faust won his first election to the Senate from a hospital bed as he was recovering from injuries sustained in a hit-and-run accident which eventually left him in a wheelchair.

Until 2023, Faust was the last person to have been a Democratic majority leader in the Michigan Senate.

While in the Senate, Faust was known for his efforts to build up state libraries and played a key role in the restoration of the Michigan State Capitol, including saving some glass panes from the ceiling of the Senate chamber.

[3] Less than a month after leaving the Senate, and after coronary bypass surgery and having his gall bladder removed, Faust died on January 21, 1995, aged 65.
