Bedok is bounded by five other planning areas: Paya Lebar to the north, Hougang to the northwest, Tampines to the northeast and east, Geylang to the west and Marine Parade to the southwest.

The area was originally a fishing village and agriculture centre, but it has transformed into a bustling residential and commercial hub over the years.

Today, Bedok is known for its vibrant and diverse community, with a mix of public and private housing options, shopping centers, parks, and a thriving food scene.

The area is also well-connected to the rest of the city, with a number of transportation options, including MRT stations, bus routes, and major expressways, making it an accessible and convenient location for residents and visitors alike.

[2][5] This high demographic is largely explained by the affordable public housing in Bedok New Town, due to its relatively distant location from the Central Area.

Besides public housing developments, private residences are also prevalent in the area, most of which are found in the neighbourhoods of Bayshore, Frankel Avenue and Siglap, in western and southwestern Bedok.

After Singapore was colonised by the British in 1819, Simpang Bedok became an ethnically mixed community consisting of Chinese and Malay peoples.

[9] In the following decade, Bedok was transformed by the Housing and Development Board (HDB) into the country's fifth self-contained new town, with the first residential flats emerging in the vicinity by 1975.

[10] Following the Fall of Saigon that same year, Bedok Jetty became a focal point for Vietnamese refugees landing in Singapore during Operation Thunderstorm.

It is bounded by Paya Lebar to the north, Hougang to the northwest, Tampines to the northeast and east, Geylang to the west, and Marine Parade to the southwest.

The Aljunied GRC covers northern Bedok along with the subdivisions of Kaki Bukit and Bedok Reservoir; its MPs were the secretary-general of the Workers' Party (WP) Pritam Singh, former NCMP Gerald Giam and Muhamad Faisal Manap, and WP had held on to the constituency since the 2011 election where it was first led by then-secretary general Low Thia Khiang.

The Marine Parade GRC covers Frankel, Kembangan, and west Siglap; its MPs are Minister Edwin Tong, and formerly Speaker Tan Chuan-Jin (2020-2023).
