U hemiji, boran je hemijsko jedinjenje bora i vodonika. Borani obuhvataju veliku grupu jedinjenja sa opštom formulom B_xH_y.^[4]^[5] Ta jedinjenja se ne javljaju u prirodi. Mnogi borani se lako oksiduju u kontaktu sa vazduhom, neki burno. Osnovni član BH₃ se zove boran. On je poznat samo u gasovitom stanju. On se dimerizuje da formira diboran, B₂H₆. Veći borani se sastoje od klastera bora koji su poliedarski, neki od njih postoje kao izomeri. Na primer, izomeri B₂₀H₂₆ su bazirani na fuziji dva desetoatomna klustera.

Najvažniji borani su diboran B₂H₆, pentaboran B₅H₉, i dekaboran B₁₀H₁₄. Razvoj hemije bor hidrida je omogućio razvoj novih eksperimentalnih tehnika i teoretskih koncepta. Bor hidridi su studirani kao potencijalna goriva za raketa i za automobilsku primenu.

Tokom zadnjih nekoliko dekada, doseg hemije bor hidrida je porastao da obuhvati atome osom bora, kao što je ugljenik u karboranima i metali u metalboranima, gde je jedan ili više atoma bora zamenjen metalnim atomima.
