I haven't seen anyone doing this kind of list so I decided to give it a try. Coming up with a list would be annoying because I don't really have one (I have a list of my top 3 saddest Disney moments though, but only one of them is from a DP Movie). Most of these are very heartbreaking so anyway here we go!

Snow White's Death/Funeral
This was an obvious choice, I didn't even have to think over my choice. Anyway whenever I watch this scene I want to cry, first of all the music in this scene is incredibly sad, second all the dwarfs are crying, the candles are weeping wax, the rain is pouring down and all the animals are looking inside with sad faces. This is the Saddest Disney Moment in my opinion.

Cinderella's Dress Is Ruined
This scene is horrible to watch. Cinderella had a chance of finally come out of the house she'd been working hard in everyday, but that chance is ruined by the fact that the stepmother orders the stepsisters to destroy Cinderella's beautiful dress.

Aurora's Death
Compared to the 2 moments above I can't say this scene is that sad, but it's still pretty sad. Anyway I felt mostly sorry for the fairies because they had taken care of Aurora for 16 years and suddenly they lose her (or so they think), it seems as if they had forgotten that she wasn't dead, but just in a deep sleep.

The Wedding Announcement
Ariel may be my least favorite DP, but this scene gets me everytime because she had reached so far with getting Eric into loving her, but all of a sudden he falls in love with Vanessa and decides to marry her the same day. This part is the closest to the original fairytale because the mermaid in the original also lost her prince because he had fallen for another girl, of course the difference is that in the original fairytale the mermaid died.

Beast's Death
This scene is very sad because I know that the Beast will be such an ugly looking human and I preferd him as a beast anyway. Did you knew that when Paige recorded this scene she was actually sobbing and one of the animators asked her if she was okay and she answered that she was alright and continued recording.

Jasmine belives Aladdin is dead
This movie doesn't really have sad moments, this is an exception though. After Aladdin was captured by the guards from the palace Jasmine goes to Jafar and tries to get Aladdin back, but when she gets to know that Aladdin is going to be executed she's so sad that she runs out to the garden crying. To me the saddest part is when Rajah comes to her and Jasmine blames herself for not getting to know Aladdin better. Aladdin may be my least favorite prince, but I felt sorry for Jasmine in this scene.

Farewell
I really dislike the ending to Pocahontas because of it being so sad. John Smith has to travel back to London and Pocahontas decides to stay in her village where she belongs, but tells John Smith that she'll always be with him. I don't need to explain much more, many people finds this scene sad and so do I

Mulan is almost killed
This scene isn't as sad as most of the other moments in this article, but still it's quite sad. Normally in these times in China a woman would get killed if she was discoverd in the army, but Mulan didn't got killed, instead the army leaves her in the snow. The saddest part is when she says "...so when I looked in the mirror I would see someone worthwhile, but I was wrong I see nothing".

Ray's Death
This scene is very sad because Ray dies quite slowly and he also says some words before dying. The saddest part is when he says "Evangelie like that too", it makes me nearly teary eyed when he says it. But this part shown below is quite sad too.

Flynn's Death
When I saw this movie in the theatre for the first time I almost got teary eyed at this point because I thought Flynn was really dead and that Rapunzel's tear wouldn't make him come back to life, but even today I believe that he'll be dead forever which of course is wrong. The saddest part is when Flynn says "You where my new dream" and Rapunzel says "And you where mine", it just makes me sad to hear that. This scene is also very similar to Beast's Death.
