Lasallian educational institutions are educational institutions affiliated with the De La Salle Brothers, a Roman Catholic religious teaching order founded by French priest Saint Jean-Baptiste de La Salle, who was canonized in 1900 and proclaimed by Pope Pius XII as patron saint of all teachers of youth on May 15, 1950. In regard to their educational activities the Brothers have since 1680 also called themselves "Brothers of the Christian Schools", associated with the Institute of the Brothers of the Christian Schools; they are often referred to by themselves and others by the shorter term "Christian Brothers", a name also applied to the unrelated Congregation of Christian Brothers or Irish Christian Brothers, also providers of education, which commonly causes confusion.
