The pro-Beijing camp, pro-establishment camp or pro-China camp is a political alignment in Hong Kong which generally supports the policies of the Beijing central government and the Chinese Communist Party (CCP) towards Hong Kong. The term "pro-establishment camp" is regularly in use to label the broader segment of the Hong Kong political arena which has the closer relationship with the establishment, namely the governments of the People's Republic of China (PRC) and the Hong Kong Special Administrative Region (HKSAR). Pro-Beijing politicians are labeled "patriots" by pro-Beijing media and "loyalists" by the rival pro-democracy camp.

The pro-Beijing camp evolved from Hong Kong's pro-CCP faction, often called "Leftists", which acted under the direction of the CCP. It launched the 1967 Hong Kong riots against British colonial rule in Hong Kong and had a long rivalry with the pro-Kuomintang bloc. After the Sino-British Joint Declaration was signed in 1984, affirming Chinese sovereignty over Hong Kong from 1997, the traditional leftists realigned themselves and unofficially formed a loose "United Front" with the conservative pro-business elites to counter the emergence of the pro-democracy camp in the 1990s and ensure a smooth transition of the Hong Kong sovereignty in Beijing's interest.

Since the handover in 1997, the pro-Beijing camp has become the major supporting force of the Hong Kong government and maintained control of the Legislative Council of Hong Kong (LegCo), having the advantage of indirectly elected functional constituencies. Going into the 2010s, the pro-Beijing camp underwent a period of diversification in which different parties emerged and targeted different voters which resulted in steady increases of the support. With various positions on specific issues, the camp generally embraces conservative values politically and Chinese nationalistic and patriotic sentiments. However, the unpopular SAR administrations and opposition to Beijing's policies toward Hong Kong have also caused the camp major losses in the 2003 and 2019 elections.

The faction in the pro-Beijing camp which evolved from the "traditional leftists" was also known as the "pro-communists" (親共人士), while the business elites and professionals who were appointed by the colonial government before 1997 were called the "pro-government camp". In the 1990s when the traditional leftists and business elites unofficially formed the loose "United Front" towards the handover in 1997, "pro-Beijing camp" has become a broader term for the whole segment. The term "pro-government camp" has also been used to describe the same segment which support the SAR government. During the unpopular administration of Chief Executive Tung Chee-hwa, the hardcore pro-government parties, mainly the Democratic Alliance for the Betterment of Hong Kong (DAB), were labelled "loyalists" by the pro-democracy camp. In recent years, a more neutral term "pro-establishment camp" is regularly in use, especially in Chinese media.

Amongst pragmatists, especially among the pro-business elites and tycoons who have been absorbed into Beijing's "United Front", have enjoyed political power and privileges, as well as economic interests, from the present political system and their close ties with the Beijing authorities. Some moderates also hope that in conceding on those issues on which China will not compromise, preserving as much as possible in the way of personal liberties and local autonomy can be achieved.

The rhetoric of the pro-Beijing camp is mostly concerned with patriotism, social stability and economic prosperity. The pro-Beijing camp generally supports universal suffrage in Hong Kong under Beijing's framework, under which only Beijing-designated "patriots" may govern Hong Kong, although the most conservative faction opposes increased democratic development in Hong Kong with the introduction of universal suffrage and see in it the creation of instability.

The pro-Beijing camp evolved from the pro-CCP faction in Hong Kong which existed since the establishment of the CCP. The 1922 Seamen's strike, led by the Chinese Seamen's Union and the 1925–26 Canton–Hong Kong strike, led by various left-wing labour unions, were the two major Communist-related labour movements in the British colony of Hong Kong. During the Japanese occupation of Hong Kong, the Communist East River guerillas were active in the Pearl River Delta.

The Hong Kong and Kowloon Federation of Trade Unions (FTU), an umbrella trade union for the local left-wing unions, was founded in April 1948. After the Communist victory in the Chinese Civil War, the local communists (土共) remained in their semi-underground status. In the early post-war days, the Hong Kong and Kowloon Federation of Trade Unions, the Chinese General Chamber of Commerce and the Hong Kong Chinese Reform Association became the three pillars of the local pro-CCP organs, following the orders of the New China News Agency, the de facto Communist China's representative in Hong Kong. Their rivals were the pro-Nationalist faction, who pledged allegiance to the Nationalist government on Taiwan. The FTU took a leading role in the Hong Kong 1967 Leftist Riots, which, inspired by the Cultural Revolution in the Mainland, aimed at overthrowing the British colonial rule in Hong Kong. The leftists lost their prestige after the riots for a period of time as the general public was against the violence attributed to the leftists, although the presence of the pro-Beijing Maoist elements remained strong in the universities and colleges throughout the 1970s, in which many of the pro-CCP university and college graduates became the backbones of the pro-Beijing camp today.
