Involuntary manslaughter is a criminal offense defined as the unintentional killing (homicide) of another person as a result of criminal negligence, recklessness, or during the commission of a misdemeanor (driving while intoxicated), infraction (speeding), or a felony crime that was not inherently dangerous. Involuntary manslaughter is usually a felony offense and often includes significant jail or prison time as potential punishment.

Involuntary manslaughter laws vary from state to state and are generally located in a state’s statutes—often in the penal or criminal code.

In Alaska, involuntary manslaughter is referred to as 'Manslaughter' under Alaska Statutes Section 11.41.120. It is defined as the unintentional killing of another person that results from recklessness or during the commission of another crime. The recklessness aspect involves a person being aware of and consciously disregarding a substantial and unjustifiable risk that the result will occur or that the circumstance exists. Manslaughter in Alaska is considered a class A felony, which is a serious offense and can result in severe penalties, including significant prison time. The exact punishment can vary based on the circumstances of the case, but a class A felony in Alaska can lead to a prison sentence of up to 20 years. It is important for individuals facing such charges to seek the counsel of an attorney who is experienced in criminal law to navigate the complexities of the case and the legal system.
