Kelowna (/kəˈloʊnə/ ^ⓘ kə-LOH-nə) is a city on Okanagan Lake in the Okanagan Valley in the southern interior of British Columbia, Canada. It serves as the head office of the Regional District of Central Okanagan. The name Kelowna derives from the Okanagan word kiʔláwnaʔ, referring to a grizzly bear.

Kelowna is the province's third-largest metropolitan area (after Vancouver and Victoria). It is the seventh-largest municipality in BC and the largest in the Interior. It is the 20th-largest metropolitan area in Canada. The city proper encompasses 214 km² (83 sq mi), and the census metropolitan area 2,902.45 km² (1,120.64 sq mi). Kelowna's population in 2025 is 165,907 in the city proper.

Nearby communities include the City of West Kelowna (also referred to as Westbank and Westside) to the west, across Okanagan Lake; Lake Country and Vernon to the north; Peachland to the southwest; and Summerland and Penticton to the south.

The exact dates of the first settlement in the Okanagan Valley are unknown, but a northern migration led to the habitation of this area some 9,000 years ago. The Indigenous Syilx people are the first known inhabitants of the region where they continue to live today.

In 1811, David Stuart travelled to the Okanagan Valley, becoming the first European to do so. Despite this, it was not until 1859 that Father Pandosy, a French Roman Catholic Oblate missionary, became the first European to settle there. Pandosy's settlement was located at l'Anse au Sable (Bay of Sand), which he named in reference to its sandy shoreline. Although the population remained small for the rest of the 19th century, sustenance fruit growing expanded in Kelowna during the 1870s, and by the 1890s, commercial agriculture had become firmly established.

Kelowna was officially incorporated on May 4, 1905, with a population of 600. The town's first mayor was Henry Raymer.

Although agriculture had become an important mark of Kelowna in the surrounding region, the town relied entirely on transportation over Okanagan Lake until 1925. In 1893, the Canadian Pacific Railway (CP) constructed the steamer SS Aberdeen on the lake, which served as the first significant transportation link between Kelowna and Penticton, greatly increasing the speed of Kelowna's growth. On September 11, 1925, CP was extended to Kelowna, ending the town's reliance on Okanagan Lake for transportation and trade.

In 1911, Chinese revolutionary Sun Yat-sen visited Kelowna for fundraising. At that time, approximately 15% of the population was ethnically Chinese.
