The Act for the Marriage of Queen Mary to Philip of Spain or Queen Mary's Marriage Act (1 Mar. Sess. 3 c. 2) was passed by the Parliament of England in April 1554 to regulate the future marriage and joint reign of Queen Mary I and Philip, son of the Holy Roman Emperor Charles V and Prince of Asturias. In reality, the Act seems to have served as a business contract between England and Spain; it specifies what Spain could expect from the union, while at the same time assuring the English that England would not become a satellite of Spain. The Act was repealed by the Statute Law Revision Act 1863.
