TheLuoyang dialect is a dialect ofZhongyuan Mandarin spoken inLuoyang and nearby parts ofHenan province.^[1]

The old Luoyang dialect served as one of historical standards of Chinese from theWarring States period into theMing Dynasty, which distinguish from the modern Luoyang dialect.^[2] It is because Luoyang switched fromSouthern toNorthern Mandarin over history. According toLü Shuxiang (1985), "InNorthern Song dynasty, the dialects at theCentral Plains are still in thesouthern variety [of Mandarin]; the predecessor of modernNorthern Mandarin began as a tiny regional dialect nearKhanbaliq".^{[3][note 1]}
