KNI A/S or Greenland Trade is a trading conglomerate in Greenland. It is the successor to the Royal Greenland Trading Department, which controlled the government of Greenland itself from 1774 to 1908 and possessed a monopoly on Greenlandic trade from 1776 to 1950. Today, the company remains a major component of the Greenlandic economy and remains fully owned by the local government. The company is based in Sisimiut (Holsteinsborg), Greenland's second-largest city, located in mid-western Greenland's Qeqqata Municipality.

The Royal Greenland Trading Department was a Danish state enterprise charged with administering the realm's settlements and trade in Greenland. The company managed the government of Greenland from 1774 to 1908 through its Board of Managers in Copenhagen and a series of Royal Inspectors and Governors in Godthaab and Godhavn on Greenland. The company was headquartered at Grønlandske Handels Plads at Christianshavn.
