Mike the Headless Chicken (April 20, 1945 – March 17, 1947) was a Wyandotte chicken that lived for 18 months after his head had been cut off. In Fruita Colorado, an annual "Mike the Headless Chicken Day" is held every May.

On September 10, 1945, farmer Lloyd Olsen of Fruita, Colorado, was planning to eat supper with his mother-in-law and was sent out to the yard by his wife to bring back a chicken. Olsen chose a five-and-a-half-month-old Wyandotte chicken named Mike. The axe removed the bulk of the head, but missed the jugular vein, leaving one ear and most of the brain stem intact.

Due to Olsen's failed attempt to behead Mike, the chicken was still able to balance on a perch and walk clumsily. He attempted to preen, peck for food, and crow, though with limited success; his "crowing" consisted of a gurgling sound made in his throat. When Mike did not die, Olsen instead decided to care for the bird. He fed it a mixture of milk and water via an eyedropper, and gave it small grains of corn and worms.

Once his fame had been established, Mike began a career of touring sideshows in the company of such other anomalies as a two-headed baby. He was also photographed for dozens of magazines and papers, and was featured in Time and Life magazines. Mike was put on display to the public for an admission cost of 25 cents. At the height of his popularity, the chicken's owner earned US$4,500 per month (equivalent to $51,525 in 2019).
