Cicero Hunt Lewis (1826–1897) was a prominent merchant and investor in Portland in the U.S. state of Oregon during the second half of the 19th century. Born in New Jersey, Lewis and a friend, Lucius Allen, traveled across the continent in 1851 to open a dry goods and grocery store in what was then a frontier town of about 800 people living along the west bank of the Willamette River. By 1880, their firm, Allen & Lewis, had become one of the leading wholesale grocery companies on the West Coast.
