John Glenn (1833 in County Mayo, Ireland – January 9, 1886 in Calgary, Alberta) was the first documented European to settle in the Calgary, Alberta, Canada area. Glenn was an Irish immigrant who first settled in the United States in 1849 and served in the American Civil War. He would then travel to British Columbia before settling in Calgary in 1873 with his wife Adelaide (née Belcourt), and built a small log cabin near the confluence of Fish Creek and the Bow River - in today's Fish Creek Provincial Park.
