Luther College is a private, comprehensive, four-year liberal arts college located in Decorah, Iowa, USA and affiliated with the Evangelical Lutheran Church in America (ELCA). Founded in 1861 by Norwegian immigrants, Luther College today boasts an enrollment of almost 2,600 students representing 34 states of the USA and 35 countries. Only about 35% of the student body represents the state of Iowa. The college offers the Bachelor of Arts degree in more than 60 majors and preprofessional and certificate programs.

Luther is perhaps the most famous for its musical groups, which have acquired global recognition through their many international tours. Since 1907 the Luther community has performed Handel's Messiah, a tradition only made longer by Bethany College. The college also hosts "Christmas at Luther" a musical celebration of the holiday season that is televised nationwide. Much of Luther's musical fame can be attributed to Weston H. Noble '43, past director of the Luther Concert Band and current Nordic Choir director. Noble has been on the Luther faculty since 1948.

In 1996 the musician Dave Matthews appeared in concert with Tim Reynolds at Luther College, the site of their 1999 album Dave Matthews and Tim Reynolds Live at Luther College. The college is also infamous for naked soccer, a final exam week tradition that ended in 2002.
