Rozini is a Brazilian musical instrument manufacturer based in São Paulo, founded in 1995 by a group of experienced luthiers. The company produces its instruments entirely in Brazil, combining small-batch serial production with hand-finishing, and has been certified by IBAMA since 2006 for sustainable wood sourcing. Its tagline, "Feito no Brasil. Tocando o Mundo." (Made in Brazil. Touching the World.), reflects its focus on instruments rooted in Brazilian musical traditions.

The brand is best known for stringed instruments tied to samba, choro, and other Brazilian styles, with a particularly broad catalog of cavaquinhos (cavacos) and seven-string classical guitars (violões de 7 cordas). Its lineup spans Studio, Pro, and Premium tiers across classical, acoustic, folk, and auditorium guitars, along with the viola caipira, bandolim, banjo, ukulele, and acoustic bass. Models are typically built with solid spruce tops over laminated backs and sides, and sold through Brazilian retailers as well as international distributors such as Kalango and Reverb sellers.

Rozini has also expanded into percussion, offering pandeiros and the tanajura, as well as gig bags, cases, and accessories. The company positions itself as a mainstream option for players of Brazilian repertoire, with instruments offered at entry-level, intermediate, and professional price points.

Rozini has 6 products cataloged on Equipboard, including Steel-string Acoustic Guitars, Acoustic-Electric Guitars, and Ukuleles. Their gear is featured by 3 artists, with the strongest followings in Rock, Folk, World, & Country, and Pop. Notable users include Rodrigo Amarante, Ziv Tamari, and Túlio Augusto.
