The Avoca starts life as two rivers, the Avonmore (Irish: Abhainn Mhór, meaning "Big River") and the Avonbeg (Irish: Abhainn Bheag, meaning "Small River"). These join together at a spot called the Meeting of the Waters (Cumar an dá Uisce) in the Vale of Avoca, which is considered a local beauty spot, and was celebrated by Thomas Moore in his song of the same name.
There is not in the wide world a valley so sweet,
The village of Avoca is situated on the river.
The Avoca flows into the Irish Sea at Arklow where it widens into a large estuary, giving Arklow its Irish language name an t-Inbhear Mór (the big inlet). The catchment area of the Avoca is 652 km2. The long term average flow rate of the Avoca is 20.2 cubic metres per second (m3/s)
The Avoca was originally called Abhainn Mhór / Abhainn Dé (great river/God's river); the present name was derived from Oboka (Greek: Οβοκα), the name of a river in Ptolemy's Geography, which was thought to correspond to the Avoca (Ovoca). Oboka more likely refers to the Liffey.
The valley of the Avoca has a large copper mine, and further downstream was the NET fertilizer factory (closed since 2002). These are said to have contributed greatly to pollution in the lower reaches of the river.
The railway line from Dublin to Rosslare also passes along the Vale of Avoca, cutting inland from its mainly coastal route and the R752 road tightly follows the west bank of the Avoca from The Meetings to Arklow.
