Haruhi Suzumiya is the central character of a series of Light Novels by Nagaru Tanigawa featuring illustrations by Noizi Ito. A first year high school student (equivalent to 10th grade/sophomore year in the USA), she is considered beautiful, athletic, intelligent, and extremely eccentric. Haruhi has come to the conclusion that ordinary humans are, as a whole, utterly boring, and that she would rather hang out with aliens, time travelers, espers, and the like. In her quest to find them, she promptly joins all the clubs in school for exactly one day... and quits them all just as rapidly. One day, her classmate Kyon (the Narrator) unwittingly gives Haruhi an idea: if there aren't any decent clubs, why not make one of your own? Haruhi instantly switches from an irritated, sociopathic, pompous brat to an irritating, sociopathic Genki Girl who vows to allow nothing to stand in her way. She conscripts Kyon to help her set up the club: the SOS Brigade, whose mission is to find aliens, time travellers, and espers, and have fun with them. Kyon quickly learns an explosive secret that must be kept from Haruhi at all costs, the details of which must be seen to be believed.
The story is notable for having no definite genre — it convincingly uses comedy, science fiction, fantasy, mystery, romance and Slice Of Life in one of the most typical anime settings: an ordinary high school, all the while with well-developed Genre Savvy characters. The SOS Brigade is made up of five members that represent a spectrum of anime character types, both in their identities as high school students and their secret identities...

The first two novels are available in English from your local online bookseller; previews (the prologue and first chapter) of both can be read at the English novel/manga website.
An anime series based on parts of the novels was released in 2006, titled after the first novel. Cries for a second season seemingly went unanswered until mid-2009, when several brand-new episodes popped up in the middle of a supposed re-run of the first season (this time done in chronological order). These new episodes constitute the "second season", and are interspersed among the old episodes according to where they chronologically belong in the plot. An English dub of the first season was produced by BANDAI Entertainment, showcasing five of the most well-known names in ADR acting. An English dub for the second season has been announced, with Cristina Valenzuela as the new Haruhi of the ASOS Brigade.
Also, a movie has been announced for novel four (The Vanishment of Haruhi Suzumiya), which may very well be the most popular one. A trailer has appeared as well.
There is a manga adaptation by Gaku Tsugano (there was an earlier adaptation by Makoto Mizuno that was discontinued/disowned after one volume). There is also a self-parody gag anime released on You Tube called The Melancholy Of Haruhi-chan Suzumiya (Suzumiya Haruhi-chan no Yūutsu) based off an official self-parody manga; this aired in tandem with a spinoff, Nyoron Churuya-san, based off a certain Yonkoma that's been subject to Memetic Mutation. There is also a Spin Off called The Vanishment of Yuki-chan Nagato (Nagato Yuki-chan no Shōshitsu) featuring Yuki Nagato as main character of a romantic Slice Of Life comedy.
If the length of this page is any indication, the anime in its first season became such a hit that it spawned unthinkable levels of praise (with resulting amounts of Hype Backlash), a globe-spanning Cash Cow Franchise, probably the largest body of Internet Backlash in the history of all anime, and made Kyoto Animation a household name.
The novels vary between several short stories and one story of several chapters, and have their differences from the anime. Usually because of the time limit the anime has, it compresses Kyon's narration process as well as the romantic focus and the character insight one would usually get from the novels, at the cost of saving comedy and the plot. While the plot alone is interesting, it leaves many actions and motives to the interpretation of the reader (often triggered by Kyon being an Unreliable Narrator), which makes you think about it long after you finish the book. However, the realistic Character Development of the Brigade members is also impressive.
If you check out the impressively big character sheet, please beware of spoilers, even if you've finished the anime.
There is also a rather substantial collection of Fan Work known collectively as Suzumiya Haruhi No Seitenkan (The Gender-Flip of Haruhi Suzumiya), which posits what would happen if all the characters in the series exchanged genders. It's worth checking out, but prepare to be confounded.
