Houston (/ˈhjuːstən/ ^ⓘ HEW-stən) is a forestry, mining and tourism town in the Bulkley Valley of the Northern Interior of British Columbia, Canada. Its population as of 2021 was 3,052, with approximately 2,000 in the surrounding rural area. It is known as the "steelhead capital" and it has the world's largest fly fishing rod. Houston's tourism industry is largely based on ecotourism and Steelhead Park, situated along the Yellowhead Highway (Highway 16). Houston is named in honour of the pioneer newspaperman John Houston.

The Morice area was first charted by amateur historian, cartographer and geologist, Reverend Adrien-Gabriel Morice (1859-1938) known to northern British Columbian locals as "Father Morice." In 1880, Morice came to British Columbia as a Catholic missionary to the native people and was one of the first 'white men' to see most of the area. Morice wrote The History of the Northern Interior of British Columbia (formerly New Caledonia) [1660 to 1880]. The Indigenous people were initially known as Carrier Indians, but today are more commonly referred to as the Wet'suwet'en (sometimes spelled Wit'suwit'en) and speak a language commonly referred to as Dakeł (Northern Athabaskan or Na-Dene language). The Morice River is called "Wet-zuhn-kwa" by the Wet'suwet'en people because of the bluish-green colour of the water.

Wet-zuhn-kwa produces fresh water species like rainbow trout, cutthroat trout, and Dolly Varden trout (bull trout). Pacific salmon species include Chinook salmon (spring or king salmon), sockeye salmon, pink salmon (humpies or humpbacks), coho salmon, and steelhead salmon, an anadromous form of the coastal rainbow trout.

The area is also rich in wildlife as it is not uncommon to spot moose, deer, black bear, grizzly bear, cougars and so on. Nanika River feeds Morice Lake and produces sockeye salmon. In the 1970s, the proposed Kemano Completion Project threatened to dam Nanika River. The project was eventually shelved. Morice River is a tributary of the Skeena river system, which is the second-largest system in BC that enters the Pacific Ocean at Prince Rupert.

In 1983, a huge forest-fire that started at Parrot Lakes threatened the community of Houston. A campfire being used by two tourists from Switzerland got out of control. The fire became known as the "Swiss Fire" and burned notable landmarks like Rose Ranch and Morice Mountain. In the post World War II era, many settlers in the region between Prince George and Prince Rupert arrived as a result of the Frontier Apostle movement.

West of Houston are Telkwa (49 kilometres or 30 miles), Smithers (66 km or 41 mi), Witset (97 km or 60 mi), Old Hazelton, New Hazelton (130 km or 81 mi), Terrace (269 km or 167 mi), and Prince Rupert (413 km or 257 mi). East of Houston are Topley (30 km or 19 mi), Granisle (79 km or 49 mi), Burns Lake (81 km or 50 mi), Fraser Lake (150 km or 93 mi), and Prince George (304 km or 189 mi).

Houston is located near the confluence of the Bulkley River and Morice River approximately 65 kilometres (40 mi) south of Smithers along Highway 16. Buck Creek also joins the Bulkley River near the community by the local mall. Historically, Buck Creek formed a delta where most of the downtown is located. The delta was channelled and dyked which probably led to the downfall and destruction of important, rearing habitat of young salmon produced in that stream.

The area is in a rain shadow of the Coast Mountains, however due to being dominated by a low pressure region, Houston receives substantial cloud cover and a mid-range volume of precipitation annually.
