The Scottish Reformation was Scotland's formal break with the Papacy in 1560, and the events surrounding this. It was part of the wider European Protestant Reformation; and in Scotland's case culminated ecclesiastically in the re-establishment of the church along Reformed lines, and politically in the triumph of English influence over that of the Kingdom of France.

The Reformation Parliament of 1560, which repudiated the pope's authority, forbade the celebration of the Mass and approved a Confession of Faith, was made possible by a revolution against French hegemony. Prior to that, Scotland was under the regime of the regent Mary of Guise, who had governed in the name of her absent daughter Mary, Queen of Scots (then also Queen of France).

The Scottish Reformation decisively shaped the Church of Scotland and, through it, all other Presbyterian churches worldwide.

From the fifteenth century, Renaissance humanism had already encouraged critical theological reflection and calls for ecclesiastical renewal in Scotland. Martin Luther's doctrinal ideas were influential in Scotland. As early as 1525 the Scottish Parliament thought it necessary to forbid the importation of Lutheran books, and to suppress 'his heresies or opinions' throughout the realm. However, this attempt was largely unsuccessful.

John Knox (c. 1514 – 24 November 1572) was a Scottish clergyman and a leader of the Protestant Reformation who brought reformation to the church in Scotland. He was educated at the University of St Andrews or possibly the University of Glasgow and was ordained to the Catholic priesthood in 1536. Influenced by early church reformers such as George Wishart, he joined the movement to reform the Scottish church. He was caught up in the ecclesiastical and political events that involved the murder of Cardinal Beaton in 1546 and the intervention of the regent of Scotland, Mary of Guise. He was taken prisoner by French forces the following year and exiled to England on his release in 1549.

While in exile, The Rev. John Knox was licensed to work in the Church of England, where he quickly rose in the ranks to serve King Edward VI of England as a royal chaplain. In this position, he exerted a reforming influence on the text of the Book of Common Prayer. In England he met and married his first wife, Marjorie. When Mary Tudor ascended the throne and re-established Roman Catholicism, Knox was forced to resign his position and leave the country.
