Enron Corporation (former NYSE ticker symbol ENE) was an American energy company based in Houston, Texas. Before its bankruptcy in late 2001, Enron employed approximately 22,000 and was one of the world's leading electricity, natural gas, pulp and paper, and communications companies, with claimed revenues of nearly $101 billion in 2000. Fortune named Enron "America's Most Innovative Company" for six consecutive years. At the end of 2001 it was revealed that its reported financial condition was sustained substantially by institutionalized, systematic, and creatively planned accounting fraud, known as the "Enron scandal". Enron has since become a popular symbol of willful corporate fraud and corruption. The scandal also brought into question the accounting practices of many corporations throughout the United States and was a factor in the creation of the Sarbanes-Oxley Act of 2002.

Enron filed for bankruptcy protection in the Southern District of New York in late 2001 and selected Weil, Gotshal & Manges as its bankruptcy counsel. It emerged from bankruptcy in November 2004 after one of the biggest and most complex bankruptcy cases in U.S. history. On September 7, 2006, Enron sold Prisma Energy International Inc., its last remaining business, to Ashmore Energy International Ltd. Following the scandal, lawsuits against Enron's directors were notable because the directors settled the suits by paying very significant sums of money personally. The scandal also caused the dissolution of the Arthur Andersen accounting firm, affecting the wider business world.

In November 2004, Enron Corp. emerged from bankruptcy pursuant to a Bankruptcy Court approved plan of reorganization. The new board of directors decided to change the name of Enron to Enron Creditors Recovery Corp., and has focused on a sole mission: to reorganize and liquidate certain operations and assets of the "pre-bankruptcy" Enron for the benefit of its creditors.
