Sanity is the character's "mental health" in Don't Starve. The Sanity icon, represented as a picture of a brain, is located near the character's Health and Hunger. Characters can gain and lose sanity in various ways. A small animated arrow appears over the icon, indicating an increase or decrease in Sanity. The size of the arrow signifies the rate of gain or loss.
As sanity decreases, the player's vision becomes shaky, over-saturated, and bright, whispers are heard, and Shadow Creatures start to appear. These creatures become "physical" and aggressive and will attack the player when their sanity is below 15%. The sign that sanity is low enough for Shadow Creatures to attack is when the player's character covers their ears and closes their eyes while rocking back and forth, as if experiencing a bad headache.
Being alone in the wilderness will take its toll. Generally speaking, being in close proximity to Monsters, Darkness, Rain, eating bad or raw Food, or using various magic items decreases sanity; while wearing certain clothing, eating Jerky and Crock Pot food, being near friendly Pigs, and sleeping increases sanity. See the Sanity Tables below for a complete list.

Characters with the potential to stay sane longer:
- Wendy - 0.75x Sanity is lost while in darkness or near monsters.
- Willow - Gains Sanity while near a fire.
- Wolfgang - 1.1x Sanity is lost while in darkness or near monsters, but this is compensated by fights being shorter if fighting while 'Mighty'.
- Maxwell - Sanity is restored at a rate of 20 (6.75 in ) in points per minute.
- Wigfrid - Gains Sanity after killing Mobs.
- Walani - Due to her drying off quicker, the combined Sanity loss from wetness would be reduced over time. She also does not have a sanity drain from Wetness itself, although she does have a sanity drain from Wet Items.
- Warly - Gains more Sanity from Crock Pot meals.
- Wilba - 1.5x Sanity is lost while in darkness, but no loss of sanity in darkness in Werepig form.
- Wormwood - Gains Sanity when planting most Plants.
- Sanity was added in the Insanity! update.
- Distortion can be turned off in the Options menu, removing the blurry effect on the edges of the screen that occurs from Sanity loss. This can also boost performance on slow systems.
- When being on Lunar Island in Don't Starve Together, Sanity becomes Enlightenment.
- In the Hamlet DLC, when being in any interior, there is no loss of sanity in Darkness.
