Borden v. United States, 593 U.S. 420 (2021), was a United States Supreme Court case involving the classification of prior convictions for "violent felony" in application of Armed Career Criminal Act (ACCA); the ACCA provides for enhanced sentencing for convicted criminals with three or more such felonies in their history.

In a 5–4 decision in June 2021, the Supreme Court ruled that crimes resulting from reckless conduct should not be considered as a "violent felony" for the purposes of the ACCA.

The District Court overruled this argument, holding that the aggravated assault offense was a violent felony, and after giving him credit for cooperation, ultimately sentenced him to nine years and seven months of imprisonment.

[1] Borden petitioned the Supreme Court, asking whether a criminal act with a mens rea of recklessness should be considered as a violent felony under the ACCA.

Kagan wrote that crimes involving the mens rea of recklessness should not be categorized as "violent felonies" for purposes of the ACCA.
