The DC101 Chili Cook-Off is an annual rock concert sponsored by Washington, D.C. / Baltimore, Maryland radio station WWDC (FM). Proceeds from the concert, traditionally held in Washington, D.C. in mid-to-late May, are donated to the National Capital Area chapter of the National Kidney Foundation. The name originates from the chili competition that used to occur during the event. Unlike what the name implies, some recent events did not actually offer any chili though in 2013 chili was offered in three different booths.
