1967.
The United States Supreme Court held laws against interracial marriage were unconstitutional in the case Loving v. Virginia, (1967). At that time 16 states still had laws prohibiting interracial marriages. That decision ended all race-based legal restrictions on marriage.

It worked the other way around: in 1967, the Supreme Court declared all State laws prohibiting interracial marriage that still existed, unconstitutional.
Before then, most 'northern' States either had never had laws prohibiting interracial marriage, or had repealed them already before 1967. It was almost all the Southern States that still had those laws in 1967.
Interracial marriages are as old as mankind. Scientific research indicates that our early homo sapiens ancestors probably mixed with Neanthertal men and women.
In Europe and later in many of its colonies, interracial marriages were taking place since the earliest days of recorded history.
In the US, many (mostly Northern) states either never had laws forbidding interracial marriage or had repealed them early on.
In 1967, the very aptly named Loving couple (Mildred and Richard) were the first interracial couple from a Southern State whose marriage was legalized by the US Supreme Court decision declaring all State laws forbidding mixed marriages unconstitutional.
All bans on interracial marriage were lifted only after an interracial couple from Virginia, Richard and Mildred Loving, began a legal battle in 1963 for the repeal of the anti-miscegenation law which prevented them from living as a couple in their home state of Virginia. It was in 1967 that this country made it illegal to limit marital unions by race.
