Boyabat is a town and district of Sinop Province in the Black Sea region of Turkey.

Boyabat has a population of 50,000 in the town itself. The town is in the Gökırmak valley located 100 km south of Sinop over the mountain range along the Black Sea coast.

The town is the trade hub for over a hundred villages around it. Of larger centers nearby, up the Gökırmak ("blue river") valley to the west is Kastamonu, down the Gökırmak and later Kızıl River valley to the east you find Samsun.

The name Boyabat is said to consist of "boy" which means border and the Persian suffix "abad" (آباد) which means built/cultivated town/agricultural landscape. It bears witness to the fact that the border between the Byzantine empire and the empire of the Seljuk Turks was once here.

Boyabat town was built below a castle which probably has not been in serious use since around 1300 A.D. but may be as old as 2800 years. The castle overlooks the Gökirmak valley. This valley is long and lies parallel with the Black Sea coast. Together with a similarly placed valley in eastern Anatolia it forms a natural east-west pathway used both in antiquity and later as part of the silk road. The older history of Boyabat may have started from Bronze Age, and it may have been ruled by Kaskians, Hittites, Paphlagonians, Persians, Lydians, Pontus kingdom, and Romans.

The area has since been under the rule of several Turkish states (: Danişmendli, Seljuk, Pervaneogullari, Candaroglular), Ottoman Empire and Turkish Republic and has been spared from major military conflicts and battles on its territory for at least 500 years.

Kazdere/Gazidere, a tributary of Gökirmak, passes through the town. It cuts the rock that the castle is perched on with a dramatic pair of vertical walls. The wall on the castle side has a window on the rock face illuminating descending tunnels for a newly discovered large underground city from roman times. The tunnels may also have served for water supply and safe passage during siege.

The main income source of the area is agriculture, animal husbandry, and some forest related activities. Of agricultural produce Boyabat is renowned for its rice. Rice fields cover the bottom of Gökirmak and Kizilirmak valleys.

The town boasts some local industry, notably brick, tiles, and ceramic production, unhusking and polishing of rice, and tanning.

Mondays a weekly bazaar is held in Boyabat center and the town overflows with farmers and merchants of the area. A larger several days long yearly event "Panayir" (fair) is held in autumn (starting the second Wednesday of October) just outside town. It lasts several days and attracts participants from a much larger area.

The local character of Boyabat is reflected in the characteristic old houses, handwoven traditional scarves popular among the farmer ladies and woodprint scarves among town ladies. Davul and zurna music is the hallmark of weddings. They lead processions through the town carrying gifts to the wedding house. On arrival, the drummer in full traditional drummer outfit performs a drumplaying dance to the music of zurna. Another Boyabat tradition kept alive is the whole grilled lamb kebab served in special restaurants. Village weddings and the panayir /fair also include a wrestling championship performed to the tune of Davul and zurna, playing non-stop, çift tokmak (5/8), epic "Koroglu" melodies.

Like every other similar town in Turkey, a large number of people originating from Boyabat now live in large metropolitan centers, mainly Istanbul some 650 km or a 10 hours bus ride away.

During the latest decades Boyabat town itself has also expanded greatly by the building of apartment blocks. The plan of the city is altered by a wide throughfare which also attracted arenas of business out from the old shopping district.

The countryside around has also seen dramatic changes. A belt of planted pine forests, a dry canal diverting flash floods away from town center, factories on the plains west of the town etc..

The construction of the Boyabat dam has started on 2008 on the Kızıl River near Duragan, a high way tunnel to avoid the highest peak of the mountain pass towards Sinop are major infrastructure projects in the area.
