Stephanie A. Gregory Clifford (born March 17, 1979),known professionally as Stormy Daniels, Stormy Waters, or simply Stormy, and named in court documents as Peggy Peterson, is an American pornographic actress, stripper, screenwriter, and director. She has won numerous industry awards, and is a member of the NightMoves, AVN and XRCO Halls of Fame. In 2009, a recruitment effort led her to consider challenging incumbent David Vitter for the 2010 Senate election in her native Louisiana.

In 2018, Daniels became involved in a legal dispute with U.S. President Donald Trump and his attorney Michael Cohen. Trump and his surrogates are alleged to have paid hush money to silence Daniels about an affair she claims she had with Trump in 2006. Trump's spokepersons have denied the affair and accused Daniels of lying.
