The Roman Catholic Diocese of San Nicolás de los Arroyos, is located in the city of San Nicolás de los Arroyos, which is usually shortened to San Nicolás, in the province of Buenos Aires, Argentina.

On 3 March 1947, Pope Pius XII established the Diocese of San Nicolás de los Arroyos from territory taken from the Diocese of La Plata and the Diocese of Mercedes. It lost territory to the Diocese of San Isidro when it was created in 1957 and the Diocese of Zárate-Campana in 1976.

The diocesan seat, the Cathedral of St Nicholas of Myra, was home to a neglected statue of Our Lady of the Rosary that had been blessed by Pope Leo XIII. The statue was rediscoverd after an image of Our Lady appeared in a vision to a local lay woman mother-of-two Gladys Motta, leading to a renewed devotion under the title Our Lady of the Rosary of San Nicolás and the erection of a new Sanctuary with hostel for pilgrims and a center for promoting popular piety. In a decree signed on May 22, 2016 and made public a few days later, Héctor Cardelli, Bishop of the Diocese of San Nicolás, declared that the apparitions that occurred over a number of years beginning in the 1980s were supernatural in origin. The devotion is thus approved "worthy of belief" at the Diocesan level within the Catholic Church.
