Nemalquinner (phonetic: nimáɬx̣ʷinix) was a Native American settlement inhabited by a band of Chinookan peoples on the east bank of the Willamette River near what is now the St. Johns neighborhood of Portland, Oregon in the United States about 2 miles (3.2 km) upstream of where the Willamette River enters the Columbia River. When encountered by the Lewis and Clark Expedition in April 1806, it was reported to have one large longhouse, a few smaller ones, and a population between 100 and 200 people. People dwelling near Willamette Falls upstream would come here to gather wapato roots.The term Nemalquinner may have also been applied to the inhabitants of this location.

Oregon Shipbuilding Corporation was a World War II emergency shipyard located along the Willamette River in Portland, Oregon, United States. The shipyard built nearly 600 Liberty and Victory ships between 1941 and 1945 under the Emergency Shipbuilding program. It was closed after the war ended. The shipyard, one of three Kaiser Shipyards in the area, was in the St. Johns neighborhood of North Portland. The two others were the Swan Island Shipyard, located several miles upriver on Swan Island; and the Vancouver Shipyard, located across the Columbia River from Portland in Vancouver, Washington.Among the ships built by Oregon Shipbuilding was the Star of Oregon, which was launched on Liberty Fleet Day, September 27, 1941. The rapid expansion of Portland area shipyards during World War II and contraction afterward caused similar expansion and contraction of the population of Vanport City, Oregon, which was also built by Henry J. Kaiser to house the workers of the three area shipyards.The former site of Oregon Shipbuilding in St. Johns is now Schnitzer Steel Industries.

St. Johns is a neighborhood of Portland, Oregon, United States, located in North Portland on the tip of the peninsula formed by the confluence of the Willamette River and the Columbia River. It was a separate, incorporated city from 1902 until 1915, when citizens of both St. Johns and Portland voted to approve its annexation to Portland, which took effect on July 8, 1915.St. Johns is bordered by the Columbia River to the northeast, the Willamette River to the northwest, the North Portland railroad cut to the southeast, and a number of streets separating it from Cathedral Park to the southwest, primarily North Ivanhoe Street.

Chimney Park is a 18.39-acre (7.44 ha) public park in Portland, Oregon's St. Johns neighborhood, in the United States. The park was acquired in 1932; formerly the site of a city incinerator, the park was named after the incinerator's chimney.

Wapato Corrections Facility (also known as the Wapato Detention Facility, and colloquially Wapato Jail) is a building that was originally built as a Multnomah County jail in 2003 in the heavy industrial area of St. Johns neighborhood of Portland.

Pier Park is a municipal park in Portland, Oregon, United States. It is in the North Portland neighborhood of St. Johns and is bordered by North Columbia Boulevard and characterized by evergreen forest. Pier Park, along with Kelley Point Park and Smith and Bybee Wetlands Natural Area, contributes land in its natural state to North Portland. The park takes its name from a person named Pier, not because it has a pier.

The Columbia Slough is a narrow waterway, about 19 miles (31 km) long, in the floodplain of the Columbia River in the U.S. state of Oregon. From its source in the Portland suburb of Fairview, the Columbia Slough meanders west through Gresham and Portland to the Willamette River, about 1 mile (1.6 km) from the Willamette's confluence with the Columbia. It is a remnant of the historic wetlands between the mouths of the Sandy River to the east and the Willamette River to the west. Levees surround much of the main slough as well as many side sloughs, detached sloughs, and nearby lakes. Drainage district employees control water flows with pumps and floodgates. Tidal fluctuations cause reverse flow on the lower slough. The Columbia floodplain, formed by geologic processes including lava flows, volcanic eruptions, and the Missoula Floods, is part of the Portland Basin, which extends across the Columbia River from Multnomah County, Oregon, into Clark County, Washington. Five percent of Oregon's population, about 158,000 people, live in the slough watershed of about 51 square miles (130 km2). Municipal wells near the upper slough provide supplemental drinking water to Portland and nearby cities. The cities, the drainage districts, the county, and a regional government, Metro, have overlapping jurisdictions in the watershed. A regional agency operates Portland International Airport along the middle slough and marine terminals near the lower slough. The Oregon Department of Environmental Quality (DEQ) and the city's Bureau of Environmental Services (BES) deal with environmental issues. Long before non-indigenous people explored the region, tribes of Native Americans fished and hunted along the slough. In the early 19th century fur trappers and explorers including Lewis and Clark visited the area before large migrations of settlers began arriving from the east. The newcomers farmed, cut timber, built houses, and by the early 20th century established cities, shipping ports, roads, rail lines and industries near the slough. Increased investment in the floodplain led to larger losses during floods, and these losses prompted levee building that greatly altered the area. A flood pouring through a levee break in 1948 destroyed the city of Vanport, which was never rebuilt. Used as a waste repository during the first half of the 20th century and cut off from the Columbia River by levees, the slough became one of Oregon's most polluted waterways. Early attempts to mitigate the pollution, which included raw sewage and industrial waste, were unsuccessful. However, in 1952 Portland began sewage treatment, and over the next six decades the federal Clean Water Act and similar legislation mandated further cleanup. State and local governments, often assisted by community volunteers, undertook projects related to public health, natural resources, and recreation in a region with many homes, industries, businesses, and roads. The businesses and industries in the watershed employ about 57,000 people, which is also frequented by more than 150 bird species and 26 fish species and animals including otters, beaver, and coyotes. One of the nation's largest freshwater urban wetlands, Smith and Bybee Wetlands Natural Area, shares the lower slough watershed with a sewage treatment plant, marine terminals, a golf course, and a car racetrack. Watercraft able to portage over culverts and levees can travel the entire length of the slough. The 40-Mile Loop and other hiking and biking trails follow the waterways and connect the parks.

Linnton is a Portland, Oregon neighborhood located between Forest Park and the Willamette River along U.S. Route 30 (NW St. Helens Rd.), close to the agricultural community of Sauvie Island.

It is the tallest bridge in Portland, with two 400-foot-tall (120 m) towers and a 205-foot (62 m) navigational clearance. The adjacent park and neighborhood of Cathedral Park are named after the Gothic Cathedral-like design of the bridge towers.
