Hulk Hogan Tyin' the Knot ... TODAY!

Hulk Hogan is about to walk down the aisle again  -- TMZ has learned the wrestling legend will marry his 35-year-old fiancée this evening at sunset.


It's all going down at the Hogan compound in Clearwater, Florida. We're told Hulk will take his girlfriend Jennifer McDaniel's hand during an intimate ceremony ... with only close friends and family invited.

Hulk's kids, Brooke and Nick, will both be in attendance -- but his ex-wife Linda didn't make the guest list.

As we first reported, Hulk applied for a marriage license last month -- and we're told L.A.-based spiritual guru Dr. Michael Beckwith will perform the ceremony.
