- “Crying helps me slow down and obsess over the weight of life's problems.”
- ―Sadness, to Joy
- “I'm to sad to walk, just give me a few... hours.”
- ―Sadness before her and Joy head into Long Term Memory
Sadness (Also known as depression); was first born when Riley was a baby; there, she met Joy, the first born emotion. When she caused baby Riley to cry, Joy pushed her aside and fixed the situation. Sadness was only used when Riley threw tantrums.
- None of the other Emotions really understand what Sadness's role is. Sadness would love to be more optimistic and helpful in keeping Riley happy, but she finds it so hard to be positive. Sometimes it seems like the best thing to do is just lie on the floor and have a good cry.
Sadness is literally the very definition and being of sorrow and gloom. She was hardly ever used because Joy is the dominant emotion and didn't want Riley to ever be sad. Because of this, Joy treated Sadness poorly. Secretly however, Sadness yearned to earn her place among the other emotions, even though the others did not believe Sadness had a purpose in the mind and almost always prevented her from trying. She is the most sensitive out of all the emotions, as she felt genuinely hurt by Joy's desertion because, "Riley needs to be happy", which made Sadness feel she was truly useless.
Sadness also complains a lot, as seen when she keeps saying she's too sad to walk or do anything.
Sadness is also smarter and has more common sense than the others, which proved expedient in the journey through Riley's mind, as she kept trying to warn Joy about the dangers of taking Bing Bong's "shortcut", which was really a dangerous place to go through, but nobody listened to her. She also suggested scaring Riley to wake her up, but Joy thought that giving her a fun dream would wake her up, which it wouldn't.
Despite her pessimistic disposition and being negative all the time, she is very considerate and compassionate towards others; when Bing Bong was sad about losing his wagon, she sympathized with him and let him tell his true feelings, which made him feel a lot happier. Unknowingly, this is because of Sadness' true purpose - her role is to tell others when Riley wants attention. When Sadness is requested to take control after Riley's sorrow became evident, she is able to let Riley express her true feelings and helps Riley find happiness at last. After the other emotions finally accept Sadness, not only does Joy start treating her better but Sadness gains more confidence in herself as well, now that she has finally found her place.
Due to Joy's obsession with keeping Riley happy, she unintentionally mistreats Sadness. As a matter of fact, the other emotions tend to exclude Sadness as well. They won't let Sadness take the wheel at all, no matter how sad the situation needs to be.
When Riley moves to San Francisco, everything starts to go bad; Riley's dad doesn't have time for her, Riley hates the house, they only serve broccoli pizza and the moving van won't come for weeks. Sadness thinks this is a good time for her to handle Riley's problems, but Joy won't let her.
The next day at Riley's new school, Joy tells Sadness to stay out of everything and stay in a small white circle made of chalk, so Riley won't be sad. When Riley is called up to introduce herself, she talks about the good old days in Minnesota and starts to cry because she misses it. It is revealed that Sadness was secretly taking the wheel and she made a new core memory that is a sad one.
The other emotions begin to panic as the sad memory gets accepted into the core memory chamber to form a new island. Joy takes the memory out and decides to throw it away. Sadness tries to stop Joy, but it causes them and the core memories to be sucked up into a tube and they end up in Long Term Memory. Joy decides to find a way to get back to Headquarters with Sadness as her guide.
During the journey, they run into Riley's old imaginary friend from toddlerhood, Bing Bong, who knows a way back to Headquarters. Joy decides to have him show them the way back. While on their way back, they go though Imagination Land, where they see that many of the childish aspects of Riley's personality are being removed, including Bing Bong's rocket that is sent down the Memory Dump. Bing Bong then is heartbroken and Joy tries to get him to stop by being goofy, but it doesn't work at all. Instead of trying to cheer him up, Sadness decides to sympathize with him and let him express his emotions. Feeling better, they continue their journey. Joy is shocked that Sadness could solve Bing Bong's problems without cheering him up instantly.
The next day, the trio finds out that Riley is running away and that all the personality islands are falling one by one. Due to Sadness' powers, Joy decides to leave Sadness behind and return to HQ, but due to some mishaps, she falls into the Memory Dump and Bing Bong comes after her.
When Joy looks at all of the forgotten memories, she sees tons of sad ones and realizes that Riley's problems were solved because Sadness was the one in control during those times and Joy finally sees that she went way overboard with trying to keep Riley happy.
Joy makes it out of the chasm, but Bing Bong sacrifices himself and fades into oblivion. Joy tries to get Sadness to come back with her, but Sadness thinks Riley doesn't need her and just cries and runs away from Joy. Soon enough, Joy is flung into the air and grabs Sadness and the two make it back to HQ, just as Riley is about to run away.
The others tell Joy to handle Riley's problem, but Joy hands the core memories to Sadness, who turns them all sad and places them in the memory holder. Riley comes home and the sad memories help her express her feelings about moving.
Just then, a new memory comes up--it's both happy and sad. Joy and Sadness hold hands on the new core memory and finally become a team and the best of friends.
Riley's First Date?
Sadly Ever After?
Sadness is set to appear in Disney INFINITY's Disney INFINITY: 3.0 Edition as a playable character.

- Sadness is the only emotion that wears a head accessory, that being her glasses.
- She is the only emotion that narrates in the Memory Dump.
- While the other four emotions have defined their function in the mind, that of Sadness is never mentioned in the film, so it could be said that its function falls under the interpretation of the viewer.
- In an early draft for the film, Sadness wasn't originally going to get lost with Joy in Riley's mind, but instead, her role would have been given to Fear.
- Sadness is the sixth female deuteragonist of Pixar. The other five are Princess Atta from A Bug's Life, Dory from Finding Nemo, Helen Parr from The Incredibles, EVE from WALL.E and Queen Elinor from Brave.
- Phyllis Smith, Sadness' voice actress, was chosen for the role of Sadness after Jonas Rivera, Inside Out's producer, noticed her performance in the 2011 film Alvin and the Chipmunks: Chipwrecked.
- Coincidentally, Sadness' voice actress, Phyllis Smith is also best known for playing Phyllis Vance in The Office.
