Panjin was established as a prefecture-level city with its current boundaries by the State Council on June 5, 1984.

Panjin is located between 40°40'−41°27' N and 121°31'−122°28' E, with its urban section mainly on the historical Liao River Delta. The Shuangtaizi River (which gives name to the city's Shuangtaizi District), formally the smaller western distributary but now the only lower section of the Liao River system, flows through the city and drains into the Liaodong Bay to its west between its Dawa District and Panshan County. The Daliao River, historically Liao River's larger eastern distributary and the main lower section but now a separate river system since 1958, runs east of Panjin, serving as the border between it and the neighboring cities of Anshan and Yingkou.

Panjin is a major crude oil production centre of Northeast China, with access to the Liaohe Oil Field, which was once the third largest oil field in China behind Daqing and Shengli Oil Fields.

Panjin has a monsoon-influenced humid continental climate (Köppen Dwa). It has an annual mean temperature of 9.2 °C (48.6 °F) and receives over 2700 hours of sunshine a year.

Major points of interest include:

• Shuangtaihekou State Natural Reserve, a marshland that serves as a natural habitat for 321 species of animals. It also serves as one of the few breeding grounds for endangered birds such as the red-crowned crane and Saunders' gull. Millions of birds of as much as 172 different species stop at the area during their migration, including more than 20 endangered species such as the red-crowned crane, demoiselle crane, white stork, black stork, white-fronted goose, whooper swan, and brown goshawk. On a special note, Panjin is also called "Home of the Cranes" for the above reasons.
