David Edward Maust (April 5, 1954 – January 20, 2006) was an American serial killer who targeted predominantly male teenagers.

Once released and off of probation he continued murdering, leading to his final arrest and sentencing to three life terms without the possibility of parole.

Jail workers found a suicide note in his cell in which he confessed to five killings, and apologized to the victims' families.

After Maust left the hospital, he came to live at a children's home where, at age 13, he was subjected to unwanted sexual advances by another boy.

Indiana Code Section 11-8-8-5(18) defines a "sex or violent offender" to include a person convicted of murder.
