(13 September 1953 – 6 August 2009) was a Mi'kmaq man who was wrongly convicted of murder.
The case inspired a number of questions about the fairness of the Canadian justice system, especially given that Marshall was Aboriginal; as the Canadian Broadcasting Corporation put it, "The name Donald Marshall is almost synonymous with 'wrongful conviction' and the fight for native justice in Canada." The case inspired the Michael Harris book, Justice Denied: The Law Versus Donald Marshall and the subsequent film Justice Denied.
His father, Donald Marshall Sr., was grand chief of the Mi'kmaq Nation at the time.
