The club was established in 1939 as a merger of amateur clubs
Corinthian (founded in 1882) and
Casuals (1883). The new club played a single match before football was suspended due to
World War II. In 1953–54 they won the
Surrey Senior Cup, beating
Epsom 2–0 in the final. Two seasons later they reached the final of the
FA Amateur Cup; after a 1–1 draw against
Bishop Auckland at
Wembley Stadium, the club lost the replay at
Ayresome Park 4–1. league reorganisation in 2002 saw them placed in Division One South. Further reorganisation saw them become members of Division One in 2004 and then Division One South again in 2006. The club returned to Brazil in 2015 to play Corinthians again, with the Brazilian club winning 3–0. In
2016–17 they finished fourth in Division One South, qualifying for the promotion play-offs. After beating
Greenwich Borough 4–3 in the semi-finals, they lost on penalties to
Dorking Wanderers in the final after a 0–0 draw. The
2017–18 season saw Corinthian-Casuals finish fifth in the division, again reaching the play-offs. They defeated
Greenwich Borough 3–0 in the semi-finals, before losing the final 4–2 on penalties to
Walton Casuals after the game ended 0–0. Despite the defeat, the club were promoted to the Premier Division after results in other divisions meant that they were the play-off finalists at step 4 with the highest points per game ratio from the season. They were relegated to the South Central Division at the end of the
2022–23 season after finishing second-from-bottom of the Premier Division. The
following season saw them finish bottom of the South Central Division, resulting in a second successive relegation, this time to the Premier Division South of the Combined Counties League. ==Ground==
