Orrefors Glassworks (also known as just Orrefors) is a glassworks in the Swedish village Orrefors in Småland. Orrefors manufactured crystal glassware and art glass. The range consisted of crystal stemware, barware, vases, and sculptures and lighting products in crystal. The glassworks in Orrefors closed in 2012.

The Orrefors glassworks were founded in 1898 on the site of an older iron works. Up until 1913, the company produced mainly window glass and bottles. When Consul Johan Ekman bought the factory in 1913, Orrefors started to produce drinking glasses, vases and other house-ware items. Ekman hired the brothers Eugen and Knut Bergkvist, who had worked at Kosta Boda before, as well as Fritz Blomqvist and Heinrich Wollman. Wollman originated from Bohemia, which had a long tradition in glassmaking. The first attempts at art glass making were in the style of the at the time famous French glassworks such Daum and Gallé.

A similar technique was devised in 1936 which trapped air within the walls of the glass. This was known as Ariel, a name of a character in Shakespeare’s play The Tempest. A major influence of theirs was the Art Nouveau work of the French artist Émile Gallé. Their designs use characteristic clean lines of brilliant crystal that suggests a frozen liquid. Their work was greatly admired when it was displayed to a wide audience at the Paris Exhibition
