The former Beverley Hills, 90210 star wed celebrity photographer Kurt Iswarienko in front of 120 guests at a simple event for which the entire congregation wore black.
The ceremony was filmed for Doherty's upcoming WE tv reality series Shannen Says, which will premiere on the network early next year.
Doherty was previously married to Ashley Hamilton for one year in 1993, and married Paris Hilton's sex tape co-star Rock Saloman in 2002 before annulling the marriage seven months later.
The actress recently said she reprised her role as Brenda for The CW's 90210 as a thank you to fans of the original series.
