Hagman -- who played the conniving J.R. Ewing on the show -- passed away in November ... and now his 3,029-square-foot ritzy beach pad has been listed by realtor David Solomon.
We're told it was the actor's primary residence at the time of his death.
The eclectic 2-bedroom condo is fit for a king ... it's one block from the beach and is rockin' panoramic ocean views, floor-to-ceiling windows, brightly colored interiors, a jacuzzi tub -- and a bedroom where the gold sheets match the wallpaper. Literally.
FYI -- Hagman's other residence is also for sale ... a massive 20,000-square-foot estate in Ojai, CA he bought back in 1987. It's listed for $6.5 million, but was on the market prior to his death.
