[[caption-width-right:350:"The stars foretell... a change in wardrobe?" [[note]]''Habit d'Astrologue'' by Nicolas de Larmessin.[[/note]]]]

This character is a pretty old staple in fiction. This characters claims to have the skill to see past, present and future events based on the position of stars and planets, often using big heaps of {{Symbolism}} to link characters and events with astrological bodies and movements. They're a type of FortuneTeller that uses telescopes, star charts and zodiac's rather than a CrystalBall or [[TarotMotifs Tarot cards]]. Typically they're a PhonyPsychic in modern non-fantasy stories, the astrologer is usually a fake, whether they will admit it or not. If they can ''actually'' divine the future through some form of RitualMagic or PsychicPowers they're effectively a {{Seer}}, and they may {{Invoke|d Trope}} the PhonyPsychic trope as a cover for their real psychic powers.

Astrologers can be good guys, neutral, self interested, or evil. In fact, a story may have two Astrologers who engage in ScryVsScry to see which can affect their vision of the future. Just like a Tarot based divinations is open to interpretation, the Astrologer may anger clients when they wrong interpret predictions or [[PortentOfDoom have unfavorable fortunes.]] This especially true when they serve a villain who may [[YouHaveFailedMe kill them for the failure]] or as [[KillTheMessenger bearer of bad news.]]

The astrologer may use the WesternZodiac or the EasternZodiac, or instead substitute a wholecloth new astrological system of meaning. This last one is especially common in fully original fantasy settings. If they ''do'' use a zodiac of some sort, they may also happily engage [[TheMatchmaker in matchmaking,]] whether they're asked to or not.

The Astrologer is not to be confused with an Astro'''n'''omer, the former studies the stars and the latter attempts to use them to explain things on earth. He is also not to be confused with the '''psychic''' as no supernatural power or abilities are involved in an Astrological reading.

!!Examples:

[[folder: Anime and Manga ]]

* In ''MoribitoGuardianOfTheSpirit'', the primary mystical advisors to the Emperor are skygazers and astrology is a part of their divination process.

[[/folder]]

[[folder: Literature ]]

* Centaurs in ''Literature/HarryPotter'' have fairly accurate predictions this way, Firenze in particular was skilled enough to teach a class in it, but even he admitted that it required a certain knack that was hard to grasp. Astro''nomy'' is also part of the Hogwarts curriculum.
* The Unseen University Professor of Astrology briefly appears in ''Discworld/TheLightFantastic'', when Trymon asks him to cast Rincewind's horoscope and thereby establish his exact location. He comes up with a paragraph of vague advice similar to a newspaper astrology column.
** Also from ''Literature/{{Discworld}}'' is Wilf, the mysterious figure who writes the astrology section of the ''Ankh-Morpork Almanack'', and may in fact be the God of Astrology.
* TadWilliams's ''Literature/MemorySorrowAndThorn'' series has astrological motifs, particularly the recurring Conqueror's Star. Also, the court of Nabban has an astrologer who makes very accurate predictions. Unfortunately, they're not very ''precise'' predictions.
* Mameha in ''MemoirsOfAGeisha'', a good guy, consults and follows her forecast very carefully.
* Gail Andrews in ''Literature/MostlyHarmless'' is an astrologer who gave advice to President Hudson and is confronted by Tricia Macmillan on the existence of a tenth planet. Her explanation is that astrology has nothing to do with actual stars and planets; they're just the arbitary source of a system of rules that gives you insight into people.
* Raymond Smullyan's ''Satan, Cantor, and Infinity'', a book of increasingly fiendish logic puzzles, includes a dig at astrology. One portion of the book is set in the court of a king who has both an astrologer and an astronomer. The astrologer is an idiot who always lies, while the astronomer is a bright, honest person.
* In ''Literature/StrangerInAStrangeLand'', Becky Vesey is a prominent astrologer who both works for Senator Douglas' wife and is a friend of Jubal's. She ends up using her seeing ability to subtly direct people's actions in what she views as a beneficial way.
** Interestingly she's not really using astrology, and even points out herself early on that she just "senses" the truth and then makes up the astrology to fit; she learned her craft from a carnival huckster. Mike later explains that she intuitively groks things. She might be a reference to 1961 celebrity astrologers such as [[http://en.wikipedia.org/wiki/Jeane_Dixon Jeane Dixon]] or [[http://en.wikipedia.org/wiki/Carroll_Righter Carroll Righter]].
* Mama Sutra in Shea and Wilson's ''Illuminatus!'', a seeress who can also tell the ''past'' - a lot more accurately than the historians can... she predicts Putney Drake's rise to the top in the criminal world, and she can also look back to a world in which the events of Tolkien's ''Literature/LordOfTheRings'' actually ''happened''....
* In the ''[[{{Belgariad}} Malloreon]]'', the Dal race studies many supernatural things, such as necromancy (as in summoning and ''speaking'' to the dead, not raising them as undead hordes) and alchemy, but the Seers are in charge of the civilisation. [[BlindSeer Blindfolded]] except when they look at "the Book of the Heavens", one of them takes the reigns of the conflict between the two opposing Prophecies.
* The engineer from PiersAnthony's ''Macroscope'' dabbles in astrology. Harold defends his hobby by pointing out that astrologers spent thousands of years refining their methods, and they were often the most highly educated people of their eras.

* Zirinka is an astrologer from the episode "Syzygy" of ''Series/TheXFiles''. The episode takes place during a rare planetary alignment and the place multiplies its effect on local people. Zirinka is a snarker who outsnarks even Mulder and her scenes are hilarious.
