League
CLG Chill Chartha play in Division 1 of the Donegal All County league and are a record 14 times league champions (1933, 1935, 1959, 1975, 1979, 1981, 1982, 1983, 1984, 1987, 2014, 2016, 2017, 2019 and 2022). The club was relegated in 2009; despite finishing a point off a league semi place, the club went down after a number of play-offs. The club made its return to the top flight after winning the Division 2 title in 2011.
In 2014, the club won the senior Division One League title for the first time since 1987, following a 5–17 to 0–10 win away to Gaoth Dobhair.[7]
Championship
The club won the Senior Championship for the first time in 1925 and the most recent was in 2017, following a 0–07 to 0–04 win over Naomh Conaill, the club's first win since 1993 (and sixth overall). In 2016, the club made its first final appearance since 1993 but lost to Glenswilly by a point. The club faced Naomh Conaill in the 2020 final, which was put on hold due to the impact of the COVID-19 pandemic on Gaelic games.
The club won the Comórtas Peile na Gaeltachta on seven occasions, the most recent being in 2024, and won the county Gaeltacht on ten occasions, the last being in 2024. The club also won the Junior Gaeltacht on two occasions, most famously in 1989, when it won both national titles at Naomh Columba.
At underage level, the club has won the County Under 21 Championship on six occasions (1972, 1973, 1974, 2011, 2013 and 2015). The club won the Minor title on four occasions (1964, 1998, 2010 and 2012), along with a lot of underage honours.[8]
