Ballinrobe (Irish: Baile an Róba, meaning 'town of the (river) Robe') is a town in County Mayo in Ireland. It is located on the River Robe, which empties into Lough Mask two kilometres to the west. As of the 2022 census, the population was 3,148. The town is in a civil parish of the same name.

Ballinrobe is considered to be one of the oldest towns in Mayo, dating to 1390. In 1337, the registry of the Dominican friary of Athenry mentions the monastery de Roba, an Augustinian friary whose restored ruins are one of the landmarks of the town today.

A Royal Patent granted to the people of Ballinrobe on 6 December 1606 by King James allowed the town to hold fairs and markets. Obtaining a market charter was an important step in the economic development of a town and required having a spokesperson who was in the king's favour. The town became the largest and most important in the area.

Market day in Ballinrobe was Monday. Each commodity had its special place in the town. Well into the mid-1900s, turf, hay, potatoes, turnips, and cabbage were sold on Abbey Street; poultry on Glebe Street; calves on Bridge Street; and cloth, flannel, woollen socks, lace, wheat, oats, and barley outside the Market House. There were special livestock fairs held at different times of the year for pigs, cattle, and sheep.

Ballinrobe Chronicle was the local newspaper published from 1866 to 1903.

On 17 May 1919, the first of the Republican law courts were set up in Ballinrobe.

The first court under the direct authority of the Dail sat at Ballinrobe, on 17 May 1920 and was reported with some pride in the national press.

Two Ballinrobe bakeries, Western Pride and Country Crust, merged in 1989 to form Irish Pride (later acquired by Pat the Baker).
