Oriel Park, Football stadium in Dundalk, Ireland.

Oriel Park is a UEFA Category 2 football stadium on the Carrickmacross Road in Dundalk, with two covered stands on opposite sides of an all-weather pitch laid in 2026. The main stand holds the dressing rooms, bars, offices and club shop; the Shed opposite houses the commentary box and main camera position. Capacity is 3,100 seated for European matches and 4,500 for domestic games.

Dundalk F.C. moved to land leased from the Casey family in 1919 and named the ground after the medieval kingdom of Airgíalla. The first visitors were Cork F.C. (formerly Fordsons), with Dundalk winning 2–1. The pitch was turned 90 degrees in 1966 and floodlights were installed in 1967. The record attendance of about 18,000 was set in 1982 for a European Cup Winners' Cup tie against Tottenham Hotspur.

The stadium's temporary name 'Casey's Field' from 2022 honors Des Casey, the Honorary President of Dundalk Football Club who had passed away. This naming reflects how deeply the club values the people who shaped its history.

The stadium is located near Dundalk-Clarke railway station and served by local bus routes, making it easy to reach by public transport. Visitors should arrive early to allow time for orientation and accessing the stands.

Oriel Park's record crowd of about 18,000 came in 1982 for a European Cup Winners' Cup tie against Tottenham Hotspur, more than four times the ground's current 4,500 domestic capacity. The club spent £40,000 on terrace repairs and improvements before that match.
