Preheat oven to 350 degrees F (175 degrees C). Spray a 9x13-inch baking dish with cooking spray.
Cook bacon in a skillet over medium heat until the edges begin to crisp, about 5 minutes; drain bacon on paper towels. Wrap each chicken breast with 2 slices of bacon in an x-shaped pattern and place into the prepared baking sheet with bacon ends underneath.
Bake in the preheated oven for 30 minutes; spread barbeque sauce over chicken breasts and bake until the juices run clear, the chicken is no longer pink inside, and an instant-read meat thermometer inserted into the thickest part of a breast reads at least 160 degrees F (70 degrees C), 10 to 15 more minutes.
