The Eastern Illinois Panthers are the men's and women's athletic teams representing Eastern Illinois University of Charleston, IL in the NCAA'sDivision I. Most Eastern Illinois teams, including the FCSfootball team, participate in the Ohio Valley Conference. The men's soccer and men's swimming and diving teams are associate members of The Summit League, and the women's rugby team (one of only three Division I and six total teams in this NCAA "emerging sport for women") is an independent. Eastern Illinois University's colors are blue and gray. The team mascot, a panther, was informally known as "Billy" until its name was officially changed to "Prowler the Panther," in 2003 and then changed back to "Billy the Panther" in 2008.
Eastern Loyalty or EIU Fight Song is the fight song for the university. The lyrics are:
We are loyal EIU, we're loyal and true –
'though the odds be great or small
we'll still be cheering you (rah! rah!)
so fight you Panthers for the glory of our dear name
fight on for Eastern, come on you Panthers win this game!
