Saint Flannan's College is an Irish co-educational secondary school located in Ennis, County Clare, which takes its name from the 7th century patron saint of the Dál gCais. Formerly an all-boys boarding school, the first girls class was entered in 2002 and in 2005 the boarding school was closed. In 2003 an extension which added over 20 new rooms to the college was completed. A measure of the expansion that has taken place over the past thirty years is that in 1962, there were some 370 pupils, 140 of whom were day boys. Only 37 teachers were in attendance. By 2004, enrollment had risen to more than 1,001 students. Staff numbers had risen to 60. In September 2002, co-ed classes were introduced in First Year. In September 2003, a new wing containing extensive new facilities was opened. In the 2010-11 school year there were 1,206 students.
