Schwarzenegger's proclamation Tuesday sets in motion a series of administrative actions, including ordering all agencies to coordinate with public health officials as needed.
The action also suspends noncompetitive bidding for contracts needed to respond to the outbreak and waives certification requirements for laboratories involved in the testing.
Schwarzenegger also cautioned that "there is no need for alarm."
The Republican governor said his priority was to limit the spread of the disease as quickly as possible.
State health officials have confirmed 13 cases of swine flu in California.
