Poltrona Frau is a furniture-maker founded in 1912 by Sardinian-born Renzo Frau in Turin, Italy, headquartered since the early 1960s in Tolentino and specializing in leather seating for interior and automotive applications. The company name combines poltrona, the Italian word for 'armchair', and Frau, the last name of its founder.

The company uses a 21-step leather tanning process (vs. industry standard ranging from 12–15 steps) where the full-grain leather is dyed through, so a surface scratch won’t reveal a lining underneath. 95% of the company's products are made by hand.

In 2014, United States–based Haworth Group purchased a controlling interest in Poltrona Frau.

In 2006, the company marketed a knock down version of its Viking chair at their SoHo, New York store.

Beginning in 2011, the company marketed a sofa designed by French architect and designer Jean-Marie Massaud—called the John-John sofa, in tribute to John F. Kennedy Jr.—followed in 2012 by the John-John bed. In 2013, the company designed and manufactured 600 seats for the Arena Corinthians in São Paulo, Brazil, the first time the company produced seats for a football stadium.

In 2012, the company held a design competition to celebrate its centenary. The competition was won by British designer Benjamin Hubert, who designed the Juliet chair.

In addition to designing seating for yachts, airplanes and helicopters, Poltrona Frau has designed leather interiors for automobiles since 1986, when Lancia asked the company to design and manufacture interiors for their new version 8.32 Thema model. Poltrona Frau has since made interiors from automotive companies ranging from Alfa Romeo, Audi, Bugatti, Lancia, Ferrari and Maserati to Mini, Fiat, Infiniti, Jaguar and Chrysler.

In 2002 the company's leathersmiths created red leather seating and pillions for a special edition of the California model of noted Italian motorcycle manufacturer Moto Guzzi, in celebration of the company's 80th anniversary.
