Yufuin (湯布院町, Yufuin-chō) was a town located in Ōita District, Ōita Prefecture, Japan. Yufuin is now a district (町) within the city of Yufu. Its elevation is approximately 400 meters above ground.

As of 2003, the town had an estimated population of 11,342 and density of 88.77 persons per km. The total area was 127.77 km.

On October 1, 2005, Yufuin, along with the towns of Hasama and Shonai (all from Ōita District), was merged to create the city of Yufu. This controversial decision resulted in the recall of the mayor and a snap election in which he regained office.

Located in a green valley beneath the spectacular Mount Yufu (由布岳, Yufudake), a short walk from the town centre is a mix of paddy fields, housing and upmarket ryokan, with a few temples. Mount Yufu, or Yufu-dake, can be hiked in about 90 minutes. A common evening sound is the rhythmic ringing of temple bells. Although still connected to its rural roots, Yufuin is a tourist town and a popular destination for coach tours. There is the picturesque Lake Kinrin and rivers flow down and across the valley. Some hotels have outdoor baths called rotenburo with a view of Mount Yufu.

Yufuin is famous for natural hot springs (温泉, Onsen), resulting in a local economy based on domestic tourism, gift shops and hot-spring bathing. Some onsen are available to day tourists, but many are strictly for overnight guests. There are also "sento", which are the traditional public baths used by locals. One of these, the Shitanyu, can be used by tourists, while the others are for use by local residents only.

The two-peaked Mount Yufu and Lake Kinrin (金鱗湖, kinrin-ko) are commonly viewed and photographed by tourists. Lake Kinrin is known for its fall leaves the steam that rises from the lake's surface on cold mornings.

Yufuin Floral Village (湯布院フローラルヴィレッジ) is another well-known tourist attraction in Yufuin. It features many small houses (acting as gift shops) modeled after the Cotswolds region of England.

With a suspension in Covid-19-related travel restrictions and the reintroduction of flights connecting Incheon International Airport and Oita Airport in 2024 for the first time in five years, Yufuin has seen a large increase in tourism from South Korea. In December, 2023, 55,000 Korean tourists stayed overnight in Yufuin, more than four times higher than pre-COVID numbers.
