Diszel (Tapolca Diszel [ˈtɒpoltsɒ ˈdisɛl]) is an outer suburb of Tapolca in Veszprém county, Hungary. Situated in the Tapolca Basin, Diszel is rich in spectacular geological heritage and historical monuments. Diszel is considered one of the most beautiful areas of the country.

Diszel has a long history. In 1920, artifacts have been found in the area from the Bronze Age, along with Roman ruins. The area was part of Pannonia province of the Roman Empire. According to popular etymology, the name Diszel was derived from the Hungarian expression "Díszhely" [ˈdiːshɛj] (fancy place), referring to its beauty. The name was first mentioned in 1247. In 1255, the settlement was mentioned officially as Terra nomine Dezl and also as nobiles de Dezl. In 1329, it was called Dyzl, which resembles the current name.

In September 1919, following the fall of the Hungarian Soviet Republic, the village was the site of a pogrom, which involved the murder of nine Jewish residents, sexual violence, looting and property destruction.

Although the settlement has been home for farmers and ranchers for centuries, Diszel has cultural significance as well. Several artists live in and in the vicinity of Diszel. Even celebrities find retreat in the surrounding hills and spend several months here each year.

Poet and literary historian István Péter Németh from Tapolca wrote several poems and articles on Diszel and its surroundings, including "Diszel 1848", "Drawing-board is my professorate", "Greeting from Csobánc", and "The Requiem of Csobánc".

Once a village, Diszel lost its municipal independence in 1977, when it became a suburb of Tapolca. Since then, it has been referred to as Tapolca-Diszel for years, which is now often written as Tapolca (Diszel).

Diszel is in the Tapolca Basin surrounded by hills of volcanic origin. The area is part of the Balaton Uplands National Park. Its proximity to Lake Balaton makes Diszel an ideal destination for both hikers and tourists.

Despite the relatively small size of the settlement, there are many sights to see. Diszel has many architectural treasures, including ancient monuments, old watermill ruins, sculptures, and exhibitions. There is a museum and two galleries in Diszel. Dating back to the 18th century, a narrow stone bridge connects the banks of Eger Creek in the center. The backyard of the Local Community Centre gives place to a sculpture exhibition. Several grave monuments of nobles as well as memorials from World War II are placed in the cemetery. In Diszel there is a riding-hall called "Lightning" (Villám Lovaspanzió [ˈvillaːm ˈlovɒʃpɒnzioː]). Riding tours are organized to the hill Csobánc, which is a nice destination not only for equestrians, but hikers and paragliders as well. On the top of the hill there are castle ruins that survived five centuries.

The "Roman bridge" of Diszel has been ordered by the then Zala county. The bridge that can be seen today has been built in summer 1793 by stonemason Károly Schraz from Sümeg.

The sculpture of the patron saint of Bohemia, St. John of Nepomuk can be found on the "Roman bridge" of Diszel.
