Jennifer Lawrence might not have been up for an Oscar this year, but that didn't stop her from crackin' open the vino and pouring herself a glass ... or two, or more perhaps.

J Law was on the move Sunday at the 90th Academy Awards -- climbing over chairs, fixing the strap on her dress and, most notably, hugging just about everyone down in the seats ... all while holding a clutch glass of white wine that looked a bit more than half full.

Truth be told, we don't know how many she had -- but it certainly seems like Lawrence was enjoying herself at the show. And on the heels of a less than stellar box office opening for her new flick "Red Sparrow" ... why not go for the booze, right?

There's other famous folks up in here, too -- Meryl Streep, Armie Hammer, Frances McDormand, the fish monster from "The Shape of Water," and on and on.

But let's be real ... this is Jennifer's show.
