The oldest human finds in Aspen Water date back to the Stone Age. In the vicinity of Ainali in particular, many finds dating to the Stone Age have been found. Haapavesi, located around Kalainen's Pyhäjoki River, was an important wilderness area during the Iron Age. Permanent settlement spread to Haapavesi in the 16th century. Residents who settled on the banks of the Pyhäjoki River came mainly from Savo, but also partly from the coast.

The earliest livelihoods of aspen were fishing, hunting and agriculture. Tar burning began in the early 17th century and was at its widest in the late twentieth century. The popularity of tar burning was mainly influenced by the favorable location of Haapavesi, the Pyhäjoki river, which crosses the municipality, made it easy to transport tar to the coast. Partly due to the large-scale tar burning, Haapavesi's industrial activities were almost non-existent for a long time. On Spa Island in the immediate vicinity of the church village, there was a health spa in 1887–1926, where mud and clay baths were provided. Water from Asko's health spring was enjoyed between the baths. The population of Haapavesi was about 4,500 in the mid-1860s. During the great years of famine, the population of the municipality fell below 4,000. By 1920, however, the population of the municipality was already over 7,000.

Haapavesi is mentioned as the chapel parish of the Pyhäjoki parish at least as early as the 1640s, when the municipality's first preaching hall was built. It was separated as an independent parish in 1863, which, however, did not materialize until 1874. The second church of the parish was built in the 1690s and the third, a wooden cruciform church, burned in 1981, in 1784. The present church of the municipality was completed in 1984.

Haapavesi is closely related to the history of Finnish skiing. The most well-known skiers in the region are Aappo Luomajoki (1845–1919), winner of the first Oulu skis (1889), Juho Ritola (1871–1959), Matti Koskenkorva (1880–1965) and Tapani Niku, who won the first Finnish skiing Olympic medal. With the success of Haapavesi skiers, the type of ski developed in Haapavesi, the so-called aspen water, which soon spread widely beyond Aspen Water. Aspen water was previously used as a so-called. longer than the forest ski (length almost 3 m) and narrower (width approx. 7 cm). Haapavetinen was popular with racers from the 1880s to the 1910s.

In 1892, Sergeant Nora Pöyhönen founded the Haapavesi School of Economics, Finland's first school of economics for girls. The original name of the educational institution was the Nursery and Cooking School, later the Household College, as well as the host school. Today, the school belongs to Haapavesi Vocational School.

After the Second World War, evacuees from Soanlahti were settled in Haapavesi. As a result, an orthodox prayer room was built in Kytökylä in 1961–1962 on the basis of the Orthodox Church Reconstruction Act.
