It is located on the south side of the Han River. South Korea's third busiest airport, Gimpo International Airport, is located in Gonghang-dong, where many flights fly to cities like Busan, Jeju, and Gwangju. The Magok Industrial Complex, located in Magok-dong, is a major hub for research and development, housing numerous R&D centers and corporate headquarters.

The earliest recorded name of the area was Jechapa-ui (齊次巴衣), which appears in the Samguk Sagi (History of the Three Kingdoms) under the Goguryeo section. Jecha (齊次) is derived from Jegye (齊戒), meaning ritual or sacrifice, while Pa-ui (巴衣) is an ancient word meaning "rock." Together, the name means "rock for offering rituals." During the Hanseong Baekje period, the Baekje king conducted rituals inside a cave at Heogabawi Rock, praying to the land gods for prosperity. This led to the name Jechapa-ui being used for the area.

During the Three Kingdoms period, the Gangseo region was occupied by both Baekje and Goguryeo. It consisted of five prefectures: Geompo-hyeon (黔浦縣), Jechapa-ui-pyeonghoepa (齊次巴衣平淮把), Dongjahol (童子忽), and Suihol-hyeon (首爾忽縣).

In 757, during the Unified Silla period, King Gyeongdeok renamed Geompo to Gimpo-hyeon (金浦縣), making it a subordinate prefecture of Jangje-gun (長堤郡).

In 1018, under King Hyeonjong of Goryeo, the region became part of Yanggwang-do (楊廣道) and was placed under Sujoo (樹州, present-day Bucheon). In 1391, during King Gongyang’s reign, Gyeonggi Province was divided into left and right regions, with all prefectures except Yangcheon-hyeon (陽川縣) incorporated into Gyeonggi Right Province.

In 1414, under King Taejong, Gimpo and Yangcheon were merged into Geumyang-hyeon (衿陽縣). However, in October of that year, the two regions were separated again, with Gimpo incorporated into Bupyeong-bu (富平府). In 1416, Gimpo regained its status as an independent prefecture. In 1632, during King Injo's reign, Gimpo was elevated to county (gun) status.

By 1895, during King Gojong's 32nd year, Korea was reorganized into 23 districts (bu), and Gimpo, Tongjin (通津), and Yangcheon became separate counties. The present-day Gangseo District was historically part of Gimpo County and the northernmost section of present-day Bucheon.

This area is part of the Gimpo Plain, located along the banks of the Han River. The underlying bedrock consists of Precambrian granite gneiss and banded gneiss, which have been eroded over a long period, forming hilly terrain. The northern region along the Han River is a floodplain with thick sedimentary deposits, historically utilized as fertile farmland through the construction of embankments. Several low residual hills remain in the hilly areas, including Gaehwa Mountain (131.2m), Maebong Mountain (117.7m), Ujang Mountain (93.6m), Gung Mountain (74.8m), and Kkachi Mountain (75m). These hills are surrounded by expansive gentle slopes. Additionally, the area is home to streams such as Gayangcheon and Banghwacheon, which flow northward into the Han River. Notably, Banghwacheon features an irrigation channel that takes advantage of the Han River's reverse flow effect.

Gangseo District experiences an average annual temperature of 13.3°C, with a January average of 0.4°C and an August average of 26.5°C. The annual precipitation is approximately 1,212.3 mm.
