Branding Hells Angels a "danger to public order", the court blamed it for inter-gang warfare in the Netherlands and singled out its use of "colours" - patches given as a reward for serious violence - for particular criticism.
Dutch prosecutors have been trying to have the club, founded in California in the late Forties, outlawed for more than a decade as the authorities pursue the bike gangs that are often enmeshed in drugs and arms smuggling.
But commentators warned that the ban, which comes after attacks with explosives in Limburg, would lead to Hells Angels splitting into smaller gangs that would be harder to police.
The same court banned the Bandidos, Hells Angels' arch-rivals, in 2017.
Judges also outlawed Satudarah, a home-grown Dutch gang, last year, -accusing it of extortion and trafficking drugs and weapons.
"Hells Angels' profile is that of the largest and most powerful motorbike club. They believe other clubs should listen to them and that leads to long-running conflicts," the court stated.
In 2015, a café favoured by a rival gang in the southern town of Kerkrade was set on fire.
In 2016 a massive brawl, in which shots were fired, broke out between Hells Angels and another gang in a Rotterdam restaurant.
The Dutch court banned both the US parent club and the local organisation.
Last week, for the first time in the Netherlands, the Amsterdam fire-service sacked a firefighter for being a member of Hells Angels. A spokesman said membership was incompatible with working for the government.
The Dutch Ministry of Defence has also announced Hells Angels members will no longer be allowed to work for it.
