Publicist Kirt Webster said Parton was at home after being treated following the accident that happened shortly before noon local time in Nashville, Tennessee.
The 67-year-old star said in a statement that she was "all good. Just a little tired and sore".
Police said the country star was in an SUV that was hit by another vehicle. Parton and the two others were taken to hospital for treatment. A news release said none of the injuries appeared to be serious.
