Apostolicam Actuositatem (Apostolic Activity), also known as the "Decree on the Apostolate of the Laity", is one of the 16 magisterial documents of the Second Vatican Council.

The final text was approved on 10 November 1965 by a vote of 2,201 to 2. On 18 November 1965, it was promulgated by Pope Paul VI, after another vote, this time of 2,340 to 2.

The purpose of the document was to encourage and guide lay Catholics in their Christian service. In this decree the Council sought to describe the nature, character, and diversity of the lay apostolate, to state its basic principles, and to give pastoral directives for its more effective exercise. The specific objectives of lay ministry are: evangelization and sanctification, renewal of the temporal order whereby Christ is first in all things, and charitable works and social aid. The decree quotes Colossians 3:17: "Whatever you do in word or work, do all in the name of the Lord Jesus Christ, giving thanks to God the Father through Him".
