A Dala horse (Swedish: dalahäst) or Dalecarlian horse is a traditional carved, painted wooden statue of a horse originating in the Swedish province of Dalarna (Dalecarlia). The Dala horse has been widely used as a toy for children. It has also become a symbol of Dalarna, as well as of Sweden in general.

Several types of Dala horses are made with distinguishing features common to the locality of the site where they are produced. One particular style has, however, become much more common and widespread than others. It is stoutly carved and was traditionally painted Iron oxide red at first. Now it is usually reddish orange with details and a harness in white, green, yellow and blue.

The carving of Dala horses as a livelihood is thought to have started in the village of Bergkarlås [sv] in central Sweden, though the nearby "horse" villages of Risa [sv], Vattnäs, and Nusnäs were also centres of horse-making. The villages were involved in the art of furniture and clock-making, and it is likely the leftover scraps of wood were put to use in the production of Dala horses. Many early Dala horses were not painted at all, but in the beginning of the 19th century painting them in a single color, white or red, became common practice. The decoration of the Dala horse has its roots in furniture painting and was perfected over the years. According to a local tale, a wandering painter in the style of kurbits came across one of these Dala horses in a farm he was decorating. When asked by one of the children why that horse was not as beautifully painted as the ones in the decorations, he painted the Dala horse in the same style. This tradition was then carried on in order to raise the market value of the Dala horses.

The earliest references to wooden horses for sale are from 1623. In the 19th century,Stikå Erik Hansson [sv] from the village Risa in the parish of Mora introduced the technique of painting with two colours on the same brush, still used today. In the book "The Wooden Horses of Sweden," the author mentions that this famous Dala painter is buried in a small churchyard in Nebraska after having immigrated to the Midwest in 1887 at the age of 64. He changed his name to Erik Erikson upon coming to America and is buried at Bega Cemetery in Stanton County Nebraska, outside of Norfolk.

While there were many horse whittlers in the early production of Dala horses, there were comparatively few horse painters. The large number of whittlers and a lack of distinguishing features makes it difficult to distinguish between different whittlers. Early painters very rarely signed their work, but they did have their own distinct pattern from which it is often possible to identify who painted a particular horse. In the 1930s, (especially after the World's Expo in Paris 1937 and World's Fair in New York 1939 in which Dala horses were shown) mass production of Dala horses started. This marks the beginning of a new era for the Dala horse, transitioning from toy to a national symbol and popular souvenir.

The Dala horse of today is still a handcrafted article, made of pine, and its pattern is about 150 years old. At least nine different people contribute their skills to create each horse. The distinctive shape of the horse is due to the usage of flat-plane style carving.

An apocryphal legend of the Dala horse is that they became the national toy in 1716. According to the legend, soldiers loyal to King Charles XII were quartered in Dalarna and carved the toys as gifts for their hosts.

In the 2003 Norwegian film Kitchen Stories, a small Dala horse is part of a joke when a character expected a real horse as a reward.
