UPM-Kymmene Corporation (Finnish: UPM-Kymmene Oyj; usually referred to simply as UPM) is a Finnish pulp, paper and timber manufacturer. UPM-Kymmene was formed by the merger of Kymmene Corporation and Repola Ltd and its subsidiary United Paper Mills Ltd in 1996. The company's oldest mill is Papeteries de Docelles located in northeastern France, which produced traditional handpaper at the end of 15th century.

UPM consists of three business groups: energy and pulp, paper, and engineered materials. The Group employs around 24,500 people and it has production plants in 16 countries. UPM shares are listed on the NASDAQ OMX Helsinki stock exchange.

UPM products include pulp, paper, plywood, sawn timber, labels and composites, bioenergy, biofuels for transport, biochemicals and nano products. The company is the world's leading producer of graphic papers and second-largest producer of self-adhesive label materials.

Due to worldwide overproduction of paper UPM announced a cost reduction program in 2006. Voikkaa paper mill in Kuusankoski was closed. Nearly 3,000 employees in Finland were laid off. After the closure the area has been transformed into Voikkaa business area.

UPM may refer to:

A company is a business organization. It is an association or collection of individual real persons and/or other companies, who each provide some form of capital. This group has a common purpose or focus and an aim of gaining profits. This collection, group or association of persons can be made to exist in law and then a company is itself considered a "legal person". The name company arose because, at least originally, it represented or was owned by more than one real or legal person.

In the United States, a company may be a "corporation, partnership, association, joint-stock company, trust, fund, or organized group of persons, whether incorporated or not, and (in an official capacity) any receiver, trustee in bankruptcy, or similar official, or liquidating agent, for any of the foregoing." In the US, a company is not necessarily a corporation.

In English law and in the Commonwealth realms a company is a body corporate or corporation company registered under the Companies Acts or similar legislation. It does not include a partnership or any other unincorporated group of persons, although such an entity may be loosely described as a company.
