English: Carly Fiorina (née Cara Carleton Sneed; September 6, 1954) is a politician, former business executive, and current chairperson of Good360. Starting in 1980, Fiorina rose through the ranks to become an executive at AT&T and its equipment and technology spinoff, Lucent. As chief executive officer of Hewlett-Packard (HP) from 1999 to 2005, she was the first woman to lead one of the top twenty U.S. companies.

In 2002, Fiorina undertook the biggest high-tech merger in history with rival computer company Compaq, which made HP the world's largest personal computer manufacturer. HP gained market share following the merger and subsequently laid off 30,000 of its American workers. By the end of 2005, the merged company had more employees worldwide than they had separately before the merger. As of February 9, 2005, HP stock had lost more than half of its value, while the overall NASDAQ index had fallen 26 percent owing to turbulence in the tech sector. On that date, Hewlett-Packard's board of directors forced Fiorina to resign as chief executive officer and chairman.

Assessments of Fiorina's business career have varied. During her time at Lucent and Hewlett-Packard, she was named by Fortune Magazine the most powerful woman in business. Later in the February 7, 2005 issue Fortune described her merger plan as "failing" and the prognosis as "doubtful". She has been described as one of the worst tech CEOs of all time, though others have defended her business leadership decisions and viewed the Compaq merger as successful over the long term.

After resigning from HP, Fiorina served on the boards of several organizations and as an advisor to Republican John McCain's 2008 presidential campaign. She won a three-way race for the Republican nomination for the United States Senate from California in 2010, but lost the general election to incumbent Democratic Senator Barbara Boxer.

On May 4, 2015, Fiorina announced on Good Morning America that she is running for President of the United States in 2016.
