Port FC

Club foundation (1967–1968)

The club was founded in 1967 as Port Authority of Thailand Football Club by Major Prachuap Suntranakul, who was the director of Port Authority of Thailand at the time. He took on the role of chairman of Port Authority of Thailand and was instrumental in helping the club during its initial years.

Golden age (1968–1980)

In 1968, Port Authority were crowned Kor Royal Cup winners, which sparked the most successful era in the club's history as they went on to win six Kor Royal Cup titles between 1968 and 1979. Port also had plenty of success in the Queen's Cup, winning it four times in succession from 1977 to 1980. Following the 1980 Queen's Cup win, Port Authority of Thailand won four trophies in 13 years.

Development of club's name and cup champions (2009–2010)

At the start of the 2009 Thai Premier League season, the club changed its name from Port Authority to Thai Port Football Club. The name change was introduced to be in line with the new Football Association of Thailand regulations that meant all teams in the top flight must be registered as limited companies.

Thai FA Cup champions

In the same year, Port ended a 16-year wait for a trophy when they were victorious in the 2009 Thai FA Cup final, where their opponents on 23 October 2009 at the Suphachalasai Stadium were BEC Tero Sasana. The match finished 1–1 after extra time, where Edvaldo scored a goal, which saw the match advance to a penalty shootout where Port won 5–4. Pipat Thonkanya scored the decisive spot kick after Thai Port keeper Pattarakorn saved BEC Tero Sasana's fifth penalty.

In the next season, Port performed a miracle in the 2010 Thai League Cup, advancing all the way to the final and facing off against Buriram United on 21 November 2010. Port became champion of the Thai League Cup after defeating their opponent 2–1. Thai Port also qualified to the 2010 AFC Cup, where they were drawn in Group H alongside Vietnamese club SHB Đà Nẵng, Singaporean club Geylang United and Hong Kong club Tai Po. On 17 March 2010, Thai Port registered their first continental win after Pitipong Kuldilok scored the only goal in the match against Tai Po at the Tseung Kwan O Sports Ground. Port finished the group stage as runners-up, thus qualifying to the round of 16. There, they faced off against Indonesian club Sriwijaya, and thrashed their opponent 4–1, thus qualifying to the quarter-finals. Thai Port was drawn against Kuwaiti club Al-Qadsia but suffered a 3–0 defeat in the second leg at the Mohammed Al-Hamad Stadium, thus knocking them out from the competition.

Darkest period (2011–2015)

The Port Authority of Thailand has been granted the rights to operate Port in the Thai Premier League.

The Football Association of Thailand or the FAT and the Thai Premier League ruled on a legal dispute between the Port Authority of Thailand and the Thai Port Company, over the operating rights of the Thai Premier League's Port. According to the ruling, the Port Authority of Thailand, the club's original owner, was granted operating rights of the team for the 2011–12 Thai Premier League season. The FAT claimed its decision was based on the fact that the club's ownership was never officially signed over to the Thai Port Company.

Meanwhile, President of Thai Port Company, Pichet Munkong, threatened to file a civil lawsuit in the court of law, citing Thai Premier League regulations which say that a state enterprise such as the Port Authority of Thailand is prohibited from operating a football club.

Pichet is planning to sue the FAT, the Thai Premier League, and the Asian Football Confederation.

However, Port will only be permitted to compete in the upcoming season of the country's top flight league, set to begin on 12 February once its operator is registered as a for-profit corporation.

It remains unclear how the Port Authority of Thailand is planning to proceed with this matter.

The ongoing boardroom disputes took their toll as Thai Port dropped to Division 1 for the first time in 2012. Investment in the team was not forthcoming as several departing players were replaced with lower quality ones. Thai Port failed to find the back of the net in almost half of their league games and were relegated on the penultimate round of fixtures when they lost 2–1 at home to Muangthong United. As Port was relegated to the 2013 Thai Division 1 League, the club was renamed to Singhtarua. They finished the season as runners-up, thus earning promotion back to the Thai top flight in 2014.

Madam Pang's takeover (2015–2023)

In 2015, Singhtarua was taken over by Nualphan Lamsam, Thai businesswoman, by signing the Memorandum of Understanding of a five-year contract with Port Authority of Thailand to control the club's management, and the club name was reverted back to Port Football Club. Nualphan, commonly known to locals as 'Madam Pang', is the majority shareholder of Muang Thai Life Insurance and the assistant secretary general of the Democratic Party, which has held power over Bangkok for over a decade. Since Port Co took over the management of the club in 2015 by Nualphan, the team's results have improved.

In 2017, Port returned to Thai League 1. Nualphan Lamsam announced the appointment of Kiatisuk Senamuang as the new head coach of the club; Kiatisuk was manager of the Thailand national team from 2014 to 2017. Kiatisuk resigned as coach of Port after just three months in charge, managing one win, six losses and three draws during his time with the club.

In 2018, ‘Madam Pang’ loosened the purse-strings significantly in the transfer window, making a clear statement to the rest of the division. There were arrivals such as winger Nurul Sriyankem from Chonburi, left-back Kevin Deeromram from Ratchaburi Mitr Phol, and most significantly, forward Dragan Bošković from Bangkok United. The club finished third in the 2018 Thai League 1 season and created history by claiming 61 points, their highest points in a single season, under manager Jadet Meelarp.

Expected to be one of the contenders for the 2019 Thai League 1 title, Port looked to be on course for a successful campaign until June, when a poor run of form led to the sacking of Jadet Meelarp. The club subsequently appointed national team assistant Choketawee Promrut as head coach and former Manchester City defender Spencer Prior as technical director, sparking a reversal of the team's form as they won five of their next six games. They also qualified for the 2019 Thai FA Cup Final for the first time in a decade.
