Teileann is the only official name. The anglicised spelling Teelin has no official status, but is still widely used.

The village is noted for fishing, scuba diving, and traditional music. It has a fine, deep harbour at Teelin Pier, which has boat-launching facilities with safe mooring. The pier was built in the early 1880s. It is an Irish-speaking community, and has been the subject of many linguistic studies.

Teileann (pronounced as 'Chellin') means 'Dish' in the Irish language.^[1] The 'dish' being referenced here is the part of Teelin Bay beside Teelin Pier, this part of the bay being circular like a dish or plate.^[1]

Teelin is home to Coláiste Aoidh Mhic Bhricne, an Irish-language college, which attracts teenagers from across the province of Ulster. The college has been open in its current existence since 1955.

Teelin was one of the first settlements to appear on maps of Ireland, as it was an important port.^[2]

Folklorist Seán Ó hEochaidh (Seán Haughey) was from Teelin.
