The guy who founded Joe's Jeans is un-Lucky in love ... he's getting divorced.

Joe Dahan's wife, Ambre, filed to end their marriage, citing the usual irreconcilable differences.

Joe -- who turned the company into a juggernaut -- is worth an estimated $15 million in stock alone.

Ambre wants a piece of the action ... she's gunning for spousal support and wants joint custody of their 2 kids -- ages 5 and 3.

They married in 2006. The date of separation puts the marriage 1 week shy of 7 years.
