The release caused an uproar among French politicians, although it didn't reveal any huge surprises or secrets.
France itself is on the verge of approving broad new surveillance powers, and is among several US allies that rely heavily on American spying powers when trying to prevent terrorist and other threats.
There was no instant confirmation of the accuracy of the documents released in collaboration with French daily newspaper Liberation and investigative website Mediapart, but WikiLeaks has a track record of publishing intelligence and diplomatic material.
WikiLeaks spokesman Kristinn Hrafnsson told The Associated Press he was confident the documents were authentic, noting that WikiLeaks' previous mass disclosures including a large cache of Saudi diplomatic memos released last week have proven to be accurate.

Hollande's office didn't comment beyond announcing Wednesday's security meeting, though his Socialist Party issued an angry statement saying the reports suggest "a truly stupefying state paranoia."
Even if the government was aware of such intercepts, the party said, that doesn't mean "that this massive, systematic, uncontrolled eavesdropping is tolerable."
There was no immediate comment from former President Jacques Chirac, also reportedly targeted by the eavesdropping.
US National Security Council spokesman Ned Price released a statement yesterday evening saying the US is "not targeting and will not target the communications of President Hollande."
"We do not conduct any foreign intelligence surveillance activities unless there is a specific and validated national security purpose," Price added. "This applies to ordinary citizens and world leaders alike. We work closely with France on all matters of international concern, and the French are indispensable partners."
