The end of Milo and Otis leaves me sobbing like a baby in a good way. Also the ending of Nights of Cabiria is beautiful and sad and uplifting all at once.

@Ben
What’s that gif from Balistik?
Heat
@Dutch: Nice choice, Night of the Living Dead.
Throwing out some I didn’t see:
Yi Yi
City Lights
The Great Dictator
Le Samourai
Poetry, the Third Man Stray Dog, and Nights of Cabiria would definitely be at the top for me. Excellent choices all around.
I would add the endings to The Hole and I Don’t Want to Sleep Alone. Ming Tsai Liang is really good at endings!
WAR HORSE (Steven Spielberg, 2011)
The last scene of The Godfather was great too.
Oh Edward Yangs The Terrorizers 
La Dolce Vita is another fav. 
But my favorites would have to be
Possession 1981 
Tied for first
Yes, Tsai has some of the best endings even though he never seems to be finished. The Wayward Cloud stands as my favorite ending, and film.
Paris, Texas
The Usual Suspects
Hell Yeah the Wayward Cloud. Def. another fav. of mine.
Best beginning as well
@David Grillo Too bad you probably wouldn’t be able to show neither of them here. lol
It is graphic but I bet I can find it.
Surely it wouldn’t be deemed pornographic. He’s objectifying the watermelon.
Frank Perry’s The Swimmer – devastating, unforgettable ending and Lancaster’s performance in the final scenes is screen acting of the highest calibre. My favourite ending ever.
The Cook, The Thief, His Wife and Her Lover
So great.
Well,there are numerous movies with magnificent endings.I mean,most great or favorite films,have great last scenes.A great ending is really important to the impact of a film.
The Dance of Death scene,in the end of Bergman The Seventh Seal is a really unforgetable one.
Sunset Blvd.,with Gloria Gaynor walking down the stairs,saying “Ι’m ready for my close-up”,is one of the best scenes easily.
The whole scene in the airport in Casablanca,with the dialogue between Bergman and Bogart on the top of it of course.
The final duel in The Good,the Bad and the Ugly is possibly the best duel in a western(or even movie in general)ever.
Last scene in Sansho the Bailiff,when he finds his old mother again,is one of the most heartbreaking scenes I’ve ever seen.
Another one,that I can never watch with dry eyes,is the last scene in Cinema Paradiso,when Toto watches the movie with the kisses that Alfredo has left to him.
The last scene in Amici Miei,when all of them start laughing in the funeral.
In the Mood for Love,when you just watch Angkor-Wat,when you expect something to happen between,although you already know that there is no chance for them to be together again.
City Lights,when the girl finally is able to see,and sees the poor Charlie.
And many,many more that I just can’t think of this moment.
Rick and Louis (Bogart & Rains) walk away in Casablanca & Ethan Edwards (Wayne) walking away from the open door in The Searchers.
i think there was a thread about this before and i said the ending of shaun of the dead is definitely my favorite..

I VITELLONI- The look on his face, a mix of fear, uncertainty and happiness-
!!
Did no one mention von Sternberg’s Morocco?
KISS ME DEADLY
!!
For the sake of avoiding spoilers, I’ll just describe the scenes and not name the movie they’re attached to. It’s more fun that way.
The mimed tennis match with the vanishing protagonist. The man playing his saxophone alone in his destroyed house. “It was in the reign of King George III that the aforesaid personages lived and quarreled — good or bad, handsome or ugly, rich or poor, they are all equal now.” The escape-boat stuck, immobile, in the pool of dead bodies. The prostitute smiling in a teenage parade. A young woman frightened by the lights in her house.
