Christian revival is a term that generally refers to a specific period of increased spiritual interest or renewal in the life of a church congregation or many churches, either regionally or globally. This should be distinguished from the use of the term "revival" to refer to a evangelistic meeting or series of meetings (see Revival meeting).

While elements such as mass conversions of non-believers and beneficial effects on the moral climate of a given culture may be involved, revivals are seen by leaders as the restoration of the church itself to a vital and fervent relationship with God after a period of decline.

Historians have different numbering and dating systems. There were "Awakenings" around the years 1727, 1792, 1830, 1857, 1882 and 1904. More recent revivals include those of 1906 (Azusa Street Revival), 1930s (Balokole), 1970s (Jesus people) and 1909 Chile Revival which spread in the Americas, Africa, and Asia among Protestants and Catholics.

Many Christian revivals drew inspiration from the missionary work of early monks, from the Protestant Reformation (and Catholic Reformation) and from the uncompromising stance of the Covenanters in 17th century Scotland and Ulster, that came to Virginia and Pennsylvania with Presbyterians and other non-conformists. Its character formed part of the mental framework that led to the American War of Independence and the Civil War.
