The president is often referred to as the "chief of state," so right now, that would be President Barack Obama. But if you are referring to the "Secretary of State," that would be Hillary Clinton.

Rice is the Secretary of State now...and there's talk of Hillary Clinton being the next one...though that's not confirmed. The Secretary of State is a high ranking government official (in the US) who is in charge of Foreign Affairs and Policy.
Robert Gates is United States Secretary of Defense and Hillary Rodham Clinton is United States Secretary of State .
What in the United States is now called the Secretary of State earlier in US history was called the Secretary of Foreign Affairs. In a way the latter title fits better with the duties of this office. The newer title of Secretary of State is not self translating into its most important function.
