Edwin N. Chapin (June 5, 1823 – July 29, 1896) was an American postmaster and newspaper publisher. An outspoken and fearless advocate, he was often in controversy, and on account of his aggressive and combative disposition, came to be called "Old Grizzly". Chapin was a strong character, prominent as a pioneer, alert in business, a vigorous, out-spoken, independent editor, welcoming and standing by whatever promised to benefit his State, county or city.
