Ylivieska is a town and a municipality of Northern Ostrobothnia region, Finland. It has a population of 14,307 (28 February 2013), and it serves as the administrative centre for Kalajokilaakso and Pyhäjokilaakso, an area with about 90,000 inhabitants.

The municipality is unilingually Finnish.

Agriculture and animal husbandry, mainly milking cows, used to be the main sources of livelihood in Ylivieska. In recent decades, the role of agriculture has reduced following the development of industry and services. Currently, Ylivieska is home to about 30 industrial enterprises, some of which are also internationally recognized in their respective niche markets.
Regionally, Ylivieska has become an important place for car buyers. There are several stores and agents selling new and used cars, and purchases average about 6,000 cars per year. Thus, the local car sales entrepreneurs have created the concept of Ylivieska being the "Autolaakso" or "car valley" of the Kalajokilaakso and neighbouring regions.

- The specialty foods of Ylivieska are maitorieska, a simple but tasty flat bread made of barley flour, milk and salt, and pepu, which only has the same ingredients as the maitorieska, but instead of being formed into flat breads and baked, pepu is boiled and pan fried. At the neighbouring municipality Sievi, a specialty food is mutti, which is actually unfried pepu.
