The Constitution of Pylyp Orlyk or Pacts and Constitutions of Rights and Freedoms of the Zaporizhian Host is a 1710 constitutional document written by Hetman Pylyp Orlyk, a Cossack of Ukraine, at this time within the Polish–Lithuanian Commonwealth.

It establishes a standard for the separation of powers in government between the legislative, executive, and judiciary branches, well before the publication of Montesquieu's Spirit of the Laws.

The Constitution limits the executive authority of the hetman, and establishes a democratically elected Cossack parliament called the General Council.
