Hedgehog in the Fog is a 1975 Soviet animated film directed by Yuri Norstein and produced by the Soyuzmultfilm studio in Moscow. The Russian script was written by Sergei Grigoryevich Kozlov, who also published a book under the same name. In 2006, Norstein published a book titled Hedgehog in the Fog, listing himself as an author alongside Kozlov.

Hedgehog (voiced by Maria Vinogradova) sets off for his evening visit to his friend the Bear Cub. Every evening, the two meet, sit on a log, have tea and count the stars. They sit over the roof of the Bear Cub's house, and the chimney divides the Bear Cubs to the right and the Hedgehogs to the left. This evening, Hedgehog is bringing Bear Cub some raspberry jam as a special treat. As Hedgehog heads out, a sinister looking eagle owl begins to stalk him, though only to be distracted by a small pool and a hollow stump that echoes. As he walks through the woods, pondering of what the Bear Cub would say when receiving the raspberry jam, Hedgehog sees a beautiful white horse, standing in the fog. Curious as to whether the horse will sink in the fog when she goes to sleep. Hedgehog decides to walk down from the small hill and explore the fog for himself, where it is so thick he can barely see his own paws. Hedgehog tried calling for the horse, but the horse didn't respond. Hedgehog was then startled by a leaf floating down with a snail riding on it, which then slid into the fog. Hedgehog picked up the leaf, but then saw a shadowy creature resembling an elephant appearing, and then disappearing, accompanied by breathing. Hedgehog placed the leaf back onto the ground and fled into the fog. Little did he know, the white horse was grazing and snorted the leaf aside. Hedgehog was then startled by a black bat, though wasn't by the Owl who just hooted at him. Hedgehog then sensed a large shape behind him. Finding a stick, and setting down his raspberry jam, he poked at the large shape to find that it is a hollow tree where the leaf came from. Examining it, he then realizes that he has lost his raspberry jam and searches frantically for it. He then found a firefly, and having it perched on a twig, he used it as a light to shine through the fog, showcasing an outlined cathedral of trees before another firefly took the firefly away, leaving Hedgehog lost in the thick fog. Hedgehog then found himself surrounded by the owl, the bat, the shadowy elephant, the snail, and the leaf, all the while hearing the Bear Cub calling his name. Becoming more and more confused and frightened until falling before a cocker spaniel, the real identity of the shadowy elephant, who just sniffed at him, yawn, and ran off when his owner whistled for him. But no soon as the dog left, he came back and placed the raspberry jam he found within Hedgehog's arms before leaving him. Hedgehog then heard the Bear Cub calling his name, and attempting to get to the Bear Cub's house through the fog, he fell into a river. He is resigned to let the river take him where it will, seeing the stars, and the white horse staring down at him. but a mysterious voice asks who is he and how did he get in the river. Hedgehog responds, then the voice (implied to belong to a fish) takes Hedgehog to shore on his back, where Hedgehog finds himself back in the woods. Hedgehog thanks his rescuer, with the voice responding "you are welcome". Hedgehog finally arrived outside the Bear Cub's house and sat on a log, where an insect clustered light glowed with a wicker chair and a teapot with a teabag standing next to it. The Bear Cub (voiced by Vyacheslav Nevinny) then arrived after frantically searching for his friend, telling him how he called and called but he didn't answer. The Bear Cub then told him that he had already warmed the samovar and had gotten out the wicker chair to make it more comfortable to count the stars, so they can drink tea and eat raspberry jam, which Hedgehog gave to the Bear Cub. He then reminded that he had gotten the twigs to put in the samovar. Hedgehog asked if the twigs were juniper twigs, which reminded the Bear Cub, before yelling to Hedgehog of who else but to count the stars with him. The two friends sit by the fire and drink their tea and eat their raspberry jam. The Bear Cub talks on and on while Hedgehog thought how nice it is to be together, but then Hedgehog thought about the white horse in the fog.

The fog effects were created by putting a very thin piece of paper on top of the scene and slowly lifting it up toward the camera frame by frame until everything behind it became blurry and white.

Soviet era children's animation and literature was faced with the task of producing politically acceptable content. Anthropologist Serguei Oushakine (Sergey Ushakin) recognizes this atmosphere of indefinite deferment in the animation, stating: "The main thing is the work of imagination, or more precisely, the terror and pleasure with which it is linked. The final scene of pleasure, to which these various phantasmal and/or realistic experiences should indeed have led, is not included in the plot." This is evident through the hedgehog's anxiety and fixation on the horse, even after he succeeds in meeting the bear for tea.

An English Dub of the film was made for Channel 4 in the United Kingdom for Christmas in 1998. Few changes were made, with strawberry jam replacing raspberry jam. Hedgehog in the Fog was ranked in a poll at the 2003 Laputa Animation Festival where 140 animators from around the world voted for the best animated films of all time. Hayao Miyazaki, acclaimed animator of Studio Ghibli stated that he drew his inspiration from many animators including Yuri Norstein. Since January 2009, the main character (the Hedgehog) from the movie has a statue in the city center of the capital of Ukraine, Kyiv. The film was spoofed in the third episode of the eighth season of the animated comedy series Family Guy, "Spies Reminiscent of Us", in 2009. The opening ceremonies for the 2014 Winter Olympics referenced this work, mentioning it in a list of signature Russian accomplishments and artists, including Fyodor Dostoevsky, Leo Tolstoy, and Sputnik. The series Kikoriki has an episode called Chiko in the Fog, reminiscent of Nornstein's cartoon in its composition and style. The 16th episode of Pokémon the Series: Sun & Moon – Ultra Legends, "Memories in the Mist!" is inspired by this work. The Cartoon Network Studios' series Summer Camp Island has an episode called "Pepper and the Fog", which is a tribute to the film.
