The Guangya (; "Expanded [Er]ya") was an early 3rd century CE Chinese dictionary, edited by Zhang Yi (張揖; Chang I; fl. 227-232) during Northern Wei. It was later called the Boya (博雅; Bóyǎ; Po-ya; "Broadened [Er]ya") owing to naming taboo on Yang Guang (楊廣), which was the birth name of Emperor Yang of Sui.
