|Full name||Clubul Atletic Oradea|
Before the World War I, the club activated only on a local and a regional level. Between 1920 and 1932 it competed in the regional championship, winning it a couple of times, in 1924 and 1925. From 1932 onwards, the divisionary level was introduced and the club took part in it. Their best performance was achieved in 1924 when they reached the national final where they faced Chinezul Timişoara, but lost 1–4.
After the war, CAO was renamed Libertatea, and played in the Liga I. In 1948 it changed its name once again, to IC Oradea, and under this name it won the Romanian championship at the end of the 1948–49 season. After this title, the club (from 1951 Progresul) made 5 consecutive appearances in Liga I, after which in 1954 it was relegated to Liga II.
Another performance was obtained in 1955, when the club reached the Romanian Cup final but lost, only to win it one year later.
In 1958 the team was relegated to Liga II, changed its name to CS Oradea, and Crişana in 1961 (with no connection to the old Crişana Oradea), and one year later succeeded to advance once again to Liga I. A short joy, because in 1963 it was relegated again and with this, the team disappeared.
Afterwards, the football in Oradea was carried on by FC Bihor Oradea.
