Portland () is the largest city in the U.S. state of Oregon and the seat of Multnomah County. It is a major port in the Willamette Valley region of the Pacific Northwest, at the confluence of the Willamette and Columbia Rivers. The city covers 145 square miles (380 square kilometers) and had an estimated population of 639,863 in 2016, making it the 26th most populous city in the United States. Approximately 2,424,955 people live in the Portland metropolitan statistical area (MSA), the 25th most populous MSA in the United States. Its Combined Statistical Area (CSA) ranks 18th with a population of 3,160,488. Roughly 60% of Oregon's population resides within the Portland metropolitan area.
Named after Portland, Maine, the Oregon settlement began to be populated in the 1830s near the end of the Oregon Trail. Its water access provided convenient transportation of goods, and the timber industry was a major force in the city's early economy. At the turn of the 20th century, the city had a reputation as one of the most dangerous port cities in the world, a hub for organized crime and racketeering.
After the city's economy experienced an industrial boom during World War II, its hard-edged reputation began to dissipate. Beginning in the 1960s, Portland became noted for its growing liberal political values, and the city has earned a reputation as a bastion of counterculture, which proceeded into the 21st century.
