Hougang United FC

The club was founded as Marine Castle United Football Club, which was formed by Newcastle United fans in the Marine Parade area in 1998. Upon successful entry into the S.League in 1998, the club struggled in its early foray in the first few years, finishing in the bottom two for the next four seasons. The club's chairman was Dilwant Singh who became the club manager and head coach of the prime league team throughout his time at the club. Marine Castle then changed its name to Sengkang Marine Football Club in 2002 and the Dilwant was succeeded by David Rowe in which Dilwant became the assistant head coach. Sengkang Marine then went on to finish in 8th position consecutively, its highest-ever finish in its short history.

Financial difficulties then forced Sengkang Marine out of the S.League in 2004, and Paya Lebar-Punggol Football Club took its place in 2005, finishing the season as a wooden spoonist. The two clubs then merged their resources from 2006 to 2010 to form Sengkang Punggol Football Club, finishing no higher than 10th.

On 1 January 2011, the chairman of Sengkang Punggol Football Club, Mr. Bill Ng, announced the changes that began the rewriting of another chapter of the football club. With improved financial status and a change in name to the present Hougang United Football Club, there has been renewed optimism among the Hougang fan base around the club's home stadium since its inception, Hougang Stadium. The club also had its fair share of marquee players in the earlier days such as Michael Currie, who formerly played for Queens Park Rangers). Conversely, Grant Holt began his early career at the club, before going on to play for upper-division clubs in England, such as Nottingham Forest and Norwich City in the English Premier League.

In November 2014, it was announced that Hougang United and Woodlands Wellington will merge for the 2015 season.

Hougang United made their AFC Cup debut in the 2020 AFC Cup but due to the COVID-19 pandemic, the tournament got cancelled thus only winning one match against Laos side, Lao Toyota 1–3 at the New Laos National Stadium in Vientiane. The Cheetahs also qualified for the 2022 AFC Cup group stage where they play all their match in a centralised venue at the Thống Nhất Stadium in Vietnam which saw Hougang United finishing 2nd out of 4th place winning 4–3 against Cambodian side, Phnom Penh Crown and defeating Laos side, Young Elephants 1–3 before suffering a heavy defeat to Vietnamese club, Viettel 5–2.

On 19 November 2022, under the lead of caretaker manager Firdaus Kassim, Hougang United defeated defending champions, Tampines Rovers 3–2 in the 2022 Singapore Cup final in which Kristijan Krajček scored a hat-trick to secure The Cheetahs their first-ever silverware.

The club also finished 5th in the Singapore Premier League in the same season which meant they failed to qualify for any continental competitions but due to their Singapore Cup win, they snatched an AFC Cup spot from fellow Singapore Premier League club, Geylang International. Hougang United started off their 2023–24 AFC Cup campaign with a trip to Kota Kinabalu facing Sabah on 21 September 2023 where they played their first fixtures in a heavy downpour which they suffered a 3–1 away loss however in the next match against Haiphong at the Jalan Besar Stadium, Hougang United bounced back from 1–0 down as Đorđe Maksimović scored a brace in the last 10 minute in the game to settled for a 2–1 victory as the Cheetahs collected the 3 points. Hougang United went on to have a great run in the 2023 Singapore Cup where they reached the final but were unable to retain their cup.
