A pastor is the leader of a Christian congregation who also gives advice and counsel to people from the community or congregation. In Lutheranism, Catholicism, Eastern Orthodoxy, Oriental Orthodoxy and Anglicanism, pastors are always ordained. In Methodism, pastors may be either licensed or ordained. Pastors are to act like shepherds by caring for the flock, and this care includes teaching.

The word "pastor" derives from the Latin noun 'pastor' which means "shepherd" and is derived from the verb 'pascere' – "to lead to pasture, set to grazing, cause to eat". The term "pastor" also relates to the role of elder within the New Testament, and is synonymous with the biblical understanding of minister. The term Pastor, Shepherd, and Elder are all the same position. The term "Senior Pastor" does not exist in scripture, but - in multi-staffed churches - is commonly used to denote the pastor who does the preaching. Many Protestant churches call their ministers "pastors".
