Kil-Kare Raceway is a motorsports complex located in Xenia Township, Greene County, near Xenia and Dayton, Ohio, USA. It first opened in 1959 and features two separate tracks: Kil-Kare Speedway, a 3/8 mile (0.6 km) asphalt oval for stock car racing and Kil-Kare Dragway, a 1/4 mile dragstrip. The oval is unconventional in shape, with the cars almost in a continuous slide between turns one and four.
The facility is affiliated with both the NHRA and NASCAR and holds events in the Whelen All-American Series as well as local events including figure 8 races. It formerly hosted races in ARCA and USAR Pro Cup Series competition.
The name Kil Kare is believed to be derived from an old resort that once stood on the property currently occupied by the raceway. A bicycle path that borders the raceway to the South was once a railroad. The railroad carried passenger trains near the turn of the century. The passenger trains stopped at the resort that was named "Kill all your cares". As time progressed, the resort closed and the name Kil-Kare stuck.
