Rize Province (Turkish: Rize ili) is a province of north-east Turkey, on the eastern Black Sea coast between Trabzon and Artvin. Its capital is the city of Rize.

Rize is on the north side of the range of mountains that run along the Black Sea coast. Overlooking the sea this is the wettest corner of Turkey and Rize is the country's largest producer of tea'. The province is mainly rural and very attractive with its mountain valleys and elevated yaylas (meadows). The district of Çamlıhemşin in particular is one of Turkey's most popular venues for trekking holidays. Within remote areas, roads are scarce and electrically powered cable cars are used to transport people and supplies into the mountains. As well as tea, nowadays kiwi fruit are grown here too. Summers are cool (July average 22°C), winters are mild (January average 7°C) and it is wet all year round.

The new Black Sea coast road is making Rize more accessible, while drawing criticism for its effect on the wildlife of the coast, and from the early 2000s, Rize has seen an increase in visitors from outside the province, particularly those seeking to escape into the countryside. This increased tourism has raised concerns among locals that the traditional way of life and the unblemished character of the natural surroundings is under threat. The provincial governor, Enver Salihoglu (as of 2005) has stated his opposition to the expansion of the road network and has advocated a commercial focus on beekeeping, trout farming, and the growing of organic teas.

Rize is the capital of Rize Province, in northeast Turkey, on the Black Sea coast.

The name comes from Greek ριζα (riza) or Ριζαίον (Rizaion)^{[citation needed]}, meaning "mountain slopes". In modern times, its name in Greek was usually Ριζούντα (Rizounta). Its Latin forms are Rhizus and Rhizaeum (which remains the name of a Catholic titular see in the province of Pontus Polemoniacus). In Ottoman period, it was called Rize (ريزه). The Georgian name is Rize (რიზე), Laz name is Rizini (რიზინი)

The first written mention of Rize is made by Arrianus in a work named Periplo (Ship's Voyage). Dated at 131-132 B.C., the work records how its author, the governor of Cappadocia, made an inspection tour of the Eastern Black Sea territories that were part of his jurisdiction, first visiting the Roman Empire's Eastern Anatolian frontier garrisons before pushing on to the Black Sea coast in the Trabzon (Trebizond) region.

The city is built around a small bay on the Black Sea coast, on a narrow strip of flat land between the sea and the mountains behind. The coastal strip is being expanded with landfill and the city is growing up the steep hillsides away from the coast. Rize enjoys a mild, extremely wet climate, vulnerable to storms coming off the Black Sea and therefore the surrounding countryside is rich with vegetation and is attracting more and more visitors every year.
