A spiritual leader for the believers in a small community. In Westerns, the preacher is usually dressed semi-formally in a black broadcloth suit, and may sport a clerical collar, depending on denomination. (Many preachers will have "no denomination given" for the broadest appeal.)
When played straight (or idealistically if you happen to be a cynic), the preacher is a Good Shepherd, a force for reason and peace in the community. He usually understands that violence is an option the law has to take sometimes, but weighs heavily against it for civilians or for less-than-emergency situations. Don't think this makes the Preacher Man an easy target, though—when push comes to shove, they'll fight for what's right with all their might. Even those who are opposed to violence in all its forms can still end a fight by putting themselves in the line of fire, as few villains are either impious enough to shoot a messenger of God or stupid enough to shoot the one person in the town everyone would be willing to defend / avenge.
Towns too small to have their own church may share a "circuit rider" with other communities in the same fix. Like the Circuit Judge, the circuit preacher moves from place to place on a schedule so that any necessary weddings, baptisms or general preachifyin' can take place once a month.
May come with a "preacher's wife", who is usually long-suffering. (Preachers weren't paid much in the Wild West, and had to work any time of day or night they were needed.) The son of a Preacher Man will most likely be either a saint or a devil.
Most often spotted at weddings, funerals and town meetings. May be called on to deliver a Suspiciously Specific Sermon.

- Preacher: Rev. Jesse Custer.
- The Quick and the Dead featured a preacher that was a Retired Gunfighter.

- Reverend Kane from the second and third Poltergeist films. Leader of a ghost army who would stop at nothing to get to Carol Anne.
- Rev. Eli Sunday, the corrupt teenage preacher from There Will Be Blood.
- In Dead in Tombstone, the preacher of Edendale has turned to drink since the town has become the Wretched Hive that is Tombstone. But he still does his best to tend to the spiritual needs of his flock, and apparently has a vision regarding the coming of Guerrero to cleanse the town.
- Rev. Spence in One Foot in Heaven is a completely straight example of this trope. He ministers to his flock, giving sermons, performing weddings and baptisms, and setting an example to the community, and he never complains when they don't pay him enough or don't maintain the upkeep on his parsonage.
- Father O'Hea fills this role in Ned Kelly, and Reverend Mitchell is a missionary in Dakota Harris.
- Rev. Gates in The Blot is rather poor himself, but still manages to distribute alms to hungry people in his congregation.
- Rev. Peabody in Breakheart Pass is a preacher being sent to minister to the men of Fort Humboldt. (Or is he?)
- John Harland in The Man from Kangaroo. After being forced to back down on delivering his first service in Kalmaroo when Braggan and his gang threaten to harm his congregants, he suffers a crisis of faith and abandons the cloth to become a station hand.
- In Shoot-Out at Medicine Bend, Bother Abraham is the preacher for the local Brethren assembly. He comes to Devlin's aid and plays a vital role in recuing Maitland and Clegg from the gallows.
- The little frontier town in Caddie Woodlawn had a circuit rider.
- David Grantland in Christy (the book and corresponding short-lived TV series) was a recent seminary graduate who tried to preach to an entire area poverty-stricken, uneducated residents of the Appalachians in 1912. His efforts were met with mixed reactions.
- Hakham Dawid is the spiritual leader for his small, five-person yeshiva in A Wolf In The Soul.
- Father Dmitri in Victoria is never anything less than supportive in the protagonist's efforts to help rehouse Christian refugees, fight tyranny and injustice, and eradicate Islam from the face of the globe.
- Little House on the Prairie: The Rev. Robert Alden, who was not only a voice of reason, reassurance and understanding but an active part in the lives of everyone in Walnut Grove. Usually a pacifist, you did not want to make him angry — as the Gallander brothers found out when they finally pressed their luck with him (and he learns that two of them had sexually harrassed Caroline Ingalls).
- Shepherd Book of Firefly has left the abbey and would like to bring the word to them as need it told. It turns out he is remarkably accurate with firearms. River even calls him "preacher-man" while 'fixing' his Bible.
- When asked if the Bible doesn't have some "pretty specific" things to say about killing, Book replies "Quite specific. It is, however, somewhat fuzzier on the subject of kneecaps."
- Reverend Samuels of Kings plays Preacher Man to an entire kingdom.
- Father Mulcahy of M*A*S*H. Who was also an accomplished boxer, a go-between with the black market, and not opposed to raising orphanage money by gambling.
- Dino Attack RPG, Dr. Noomi Shaw is the closest person on the team to this sort of character. While not actually a priest, she does wear a cross and tries to use her faith as a means of comfort both for herself and those around her.
