Chinese Brazilians (Portuguese: Sino-brasileiro or Chinês-brasileiro; Chinese: 巴西華人 / 巴西华人) are Brazilians of Chinese ancestry or birth. The ethnic Chinese population in Brazil was estimated to be approximately 250,000 in 2007.

The first Chinese people came to Brazil in 1814, when Chinese tea planters were sent from Portugal to the Royal Botanical Garden in Rio de Janeiro. Following the end of transatlantic slave trade in 1850, there was a growing labor shortage in the booming coffee plantations of southwestern Brazil during the second half of the 19th century, which led the Brazilian government to look for alternative sources of labor elsewhere. The main sources of replacement labor were Europe and, later on, Japan, but small numbers of Chinese immigrants are said to have reached Brazil during the 19th century (less than 3 thousand total). There are reports of Chinese laborers arriving in Brazil exist as early as the 1870s, but those early flows were limited due to restrictions imposed by the Chinese government; therefore, the vast majority of the contemporary population of Chinese ancestry in Brazil is descended of much later flows of immigrants into the country, starting in the 1900s.

São Paulo now has the largest Chinese Brazilian population, in particular in the district of Liberdade. The majority of the Chinese immigrants settle in São Paulo. Some Chinese immigrants work as merchants for international trade, lawyers, members of the parliament and the house of representatives and doctors. Chinese immigrants have integrated into the Brazilian society by building inter-cultural exchange in the communities. Besides being an area famous for its strong Japanese presence, a significant number of Taiwanese immigrants out of 70,000 in total, have settled in Liberdade, and many Chinese immigrants have come to Liberdade following the Communist revolution in 1949. These Macau immigrants can usually speak and understand Portuguese (its Creole, Macanese or Patuá, is also spoken), allowing them to adjust more easily to life in Brazil. In the 1950s, there was also a wave of Chinese immigrants belonging to the country's ethnic Russian community.

Today, the majority of Chinese Brazilians only speak Portuguese, although some may be bilingual, speaking Portuguese and Chinese.

It is known that there were Chinese in Brazil as far back as the early 19th century; Rugendas painted a depiction of Chinese Tea planters in Rio de Janeiro during the period of the Portuguese Royal family in Brazil. In 1814 John VI of Portugal brought 300 Chinese from Macau to work in the Botanical Garden of Rio de Janeiro.

Chinese people started moving to Brazil in the late 19th century when Brazil abolished the slave trade, which had as a necessary consequence the eventual doom of slavery. As a result, the number of Afro-Brazilians slaves decreased gradually, which created labor shortages. To solve the problem, the Brazilians came up with a plan of having immigrants to the country to replace the slaves. The Brazilian government and plantation owners started looking to different areas of the world to try to find suitable groups to import into the country, Europe ended up being the most relevant, and, later on, Japan and the Ottoman Empire were also major sources of immigration to Brazil, but India and China were also considered.

In this context, the Brazilian government also considered importing Chinese laborers, just like other tropical nations which had done the same since the 1840s. However, as China had known that the Chinese laborers had received harsh labor treatments in countries like Cuba and Peru, China had prohibited all other forms of immigration but the voluntary ones, and allowed importation of laborers only to countries with commercial treaties. Despite the barriers set by the Chinese government, Brazilian companies still managed to have 1,000 Chinese to work as tea planters in 1874. In 1875, the Brazilian companies tried to bring in more Chinese workers to Brazil by recruiting those in the province of Guangdong (Canton) and California. To legally import more Chinese laborers, the Brazilian government negotiated a commercial treaty with China, but China signed the commercial treaty with reluctance in Tianjin, China on September 5, 1880 with a revised contract on October 3, 1881. With the low cost of transportation that is 35 milreis per passenger, which was less than 20 U.S dollars, the new Brazilian companies tried to seek more laborers from China by connecting with the director of the China Merchants Steam Navigation Company called Tong King Sing. Despite the plans to transport more Chinese laborers to Brazil, the Chinese government continued displaying hesitant attitude in the 1890s. Therefore, China was not a viable alternative for Brazil in its search for new sources of labor in the second half of the 19th century and early 20th century.

The issue of how to replace slave labor raised huge controversies in Brazil, and there were both sides that defended and criticized the alternative of inviting in Chinese immigrants to work in the coffee plantations One such argument that was a cause of much controversy was the idea of racial "whitening", which is a concept inspired in the ideas of Social Darwinism and eugenics that defended the need to import more European immigrants into Brazil in order to "whiten" its population. In this context, the idea of inviting Asian workers, including those of Japanese and Chinese origin, was seen by some as a possible set back that could harm the process of "europeanizing" Brazil, due to perceived cultural and racial inferiority to the Europeans, and feared the consequences of introducing "alien populations" that did not match the traditional composition of the Brazilian population at the time (mostly of European and African ancestry). On the other hand, some, such as the Republican leader Quintino Bocayuva, defended the notion that having Chinese laborers would benefit Brazil.
