The Luoyang dialect is a dialect of Zhongyuan Mandarin spoken in Luoyang and nearby parts of Henan province.
The old Luoyang dialect served as one of historical standards of Chinese from the Warring States period into the Ming Dynasty, which distinguish from the modern Luoyang dialect. It is because Luoyang switched from Southern to Northern Mandarin over history. According to Lü Shuxiang (1985), "In Northern Song dynasty, the dialects at the Central Plains are still in the southern variety [of Mandarin]; the predecessor of modern Northern Mandarin began as a tiny regional dialect near Khanbaliq".[note 1]
