Cosimo Fini (born 25 December 1980), known professionally as Guè (Italian: [ˈɡwe]), previously as Gué Pequeno, is an Italian rapper. He is also a member of the famous hip hop group Club Dogo with rapper Jake La Furia and producer Don Joe. Between 1999 and 2001, he was also in "Sacre Scuole", a group made up by Gué Pequeno, Dargen D'Amico and Jake La Furia. In his career he collaborated with international artists such as Benny the Butcher, Kool G Rap, Akon, Rick Ross and Jadakiss.

With the initial pseudonyms of "Lucky Luciano" and "Il Guercio" (The One-eyed), the rapper started his musical career around 1997, when he met Jake La Furia. The friendship between the two leads to the creation of "Sacre Scuole", to which is added Dargen D'Amico, the latter previously classmate of Pequeno. Meanwhile, beatmaker Don Joe becomes their close collaborator. The trio released the 3 MC's al Cubo mixtape, and then disbanded due to contrasts between D'Amico and La Furia. This will lead to D'Amico leaving, and the remaining members, together with Don Joe, will subsequently give birth to Club Dogo.

Pequeno also took part in the production of several albums and mixtapes in those years, including 50 Emcee's Pt. 1 by ATPC and Tutti x uno by DJ Enzo.

In 2005 Gué Pequeno released the EP Hashishinz Sound Vol. 1 together with the Italian-Angolan producer Deleterio, nowadays known as Del, while the following year he published the Fastlife Mixtape Vol. 1, recorded with DJ Harsh. Three years later, he released the sequel, Fastlife Mixtape Vol. 2: Faster Life.

Over the years he has collaborated with the major artists of the underground and non-underground scene, including Noyz Narcos from TruceKlan, J-Ax, Marracash and Entics. In 2010 he published the book La legge del cane (The Law of the Dog), written together with Jake La Furia. In March 2011, he aired on Deejay TV with the program "Un giorno da cani" (Dogs days), a four-part television format where he and Jake La Furia turn working experiences into lyrics for their songs.

In June 2011, his first solo album was released, entitled Il ragazzo d'oro (The Golden Boy), which had the participation of several Italian rappers, including Marracash, Entics, Ensi and Jake La Furia. The disc was anticipated by the singles "Non lo spegnere" (Do not turn it off) and subsequently the video clip for the song "Ultimi Giorni" (Last days).

Also in 2011, the rapper together with DJ Harsh founded the independent record label "Tanta Roba", whose first product was Il mio primo disco da venduto (My first sellout record), by Fedez. Fastlife Mixtape Vol. 3 was also released on 20 January 2012, the result of collaboration with DJ Harsh and other Italian artists of the genre such as the aforementioned Fedez, Emis Killa, Salmo, Gemitaiz and Daniele Vit.

On 28 March 2013, the mixtape Guengsta Rap was released for free download from its official website. The tracks on the album are mixed by DJ Jay-K.
