Puck County (Polish: powiat pucki, Kashubian: pùcczi pòwiat) is a unit of territorial administration and local government (powiat) in Pomeranian Voivodeship, northern Poland, on the Baltic coast. The powiat of this name existed in the history of Poland, since the times of the Polish–Lithuanian Commonwealth up to 1795, and then reintroduced in 1999.

The modern Puck County came into being on January 1, 1999, as a result of the Polish local government reforms passed in 1998. Its administrative seat is the town of Puck, which lies 40 kilometres (25 mi) north of the regional capital Gdańsk. The county contains three other towns: Władysławowo, 16 km (10 mi) north of Puck, Jastarnia, 18 km (11 mi) east of Puck, and Hel, 29 km (18 mi) east of Puck, at the tip of the Hel Peninsula.

The county covers an area of 577.85 square kilometres (223.1 sq mi). As of 2019 its total population is 85,211, out of which the population of Puck is 11,213, that of Władysławowo is 9,930, that of Hel is 3,267, that of Jastarnia is 2,704, and the rural population is 58,097.

The railway network in the area of this county consists of two active railway lines, 213 and dismantled 263. The lines intersected in Swarzewo.

The station in Puck was located closest to the sea on the Polish railway network, which is why a temporary harbor with a railway siding was built in Puck. The development of railways in the county in the 1920s caused the development of tourism on Hel Spit. Because of the largely tourist traffic on Hel Spit, line 213 shows high seasonal variability of transports. Freight traffic, due to the lack of industry, is marginal.
