The civil lawsuit was filed on Thursday, local time, to a court in Santa Fe, in the state of New Mexico.
Baldwin is accusing two prosecutors and investigators from the sheriff's office in Santa Fe of having prosecuted him without having legal grounds for it, and for having violated his civil rights.
"The defendants tried at every opportunity to make Baldwin a scapegoat for others' actions and omissions, regardless of the evidence or the law," it states in the lawsuit.
The two prosecutors, Mary Carmack-Altwies and Kari Morrissey, have not commented on the lawsuit.
It was in October 2021 that Alec Baldwin fired a shot that killed photographer Halyna Hutchins and injured director Joel Souza during the filming of the movie "Rust". The gun, which was supposed to be loaded with blank rounds, turned out to be live.
Baldwin was charged with involuntary manslaughter, but the trial was dropped in July due to allegations that the police and prosecutors had withheld evidence from the defense.
The film's armorer, 24-year-old Hanna Gutierrez Reed, has previously been sentenced to one and a half years in prison for involuntary manslaughter.
