Josep Maria Bayarri i Hurtado (; 1886–1970 in Alboraya), also known as Xusep Maria Vaiarri, was a writer and poet.
He studied at the San Carlos School of Fine Arts before releasing in 1915 his first publication, a collection of Valencian poetry, , featuring various poets of his generation. He later helped found two poetry magazines in the Valencian language, (1934) and (1939).
During several stages of his literary life he attempted to impose linguistic norms upon Valencian, based on the (Central Valencian) dialect instead of Standard Valencian. One such was the 1966 book . These attempts, however, met with little success.
His last work, published in the year of his death, was (1970).
