Ma Xiangbo (traditional Chinese: 馬相伯; simplified Chinese: 马相伯; pinyin: Mǎ Xiàngbó; Wade–Giles: Ma³ Hsiang⁴-po²; April 7, 1840 – November 4, 1939) was a Chinese former Jesuit priest, scholar and educator in late-Qing and early-Republican China. He was one of the founders of Aurora University, Fu Jen Catholic University and Fudan University.

Ma Xiangbo's original given name was Jianchang (建常) but was changed to Liang (良). "Xiangbo" was his courtesy name. He also adopted the Catholic name Joseph.

Ma Xiangbo was born in Dantu, Jiangsu province to a prominent Catholic family. At the age of 11, he enrolled in a French Jesuit school in Shanghai, Collège Saint-Ignace (now Xuhui High School), where he remained first as student and later as teacher until 1870.

In 1870, he was ordained priest in the Jesuit order. Ma left the order and priesthood because of its discrimination against Chinese clergy. Ma remained active in Chinese Catholic circles. After leaving the priesthood, he worked in civil service with his brother Ma Jianzhong.Both brothers led significant political lives, with Jiangzhong working as a prominent official in the Qing government and Xiangbo serving as a diplomat from 1881 to 1897 in various postings in Asia including Japan (Tokyo 1881, Yokohama 1892), Korea (1882-1885?), Europe (Britain and France 1886–1887) and the United States.

In 1886/87, he visited France and eventually devoted his life to higher education.

Ma was a major proponent of Catholic education in China. In 1903, Ma donated funds to found Aurora University (Zhendan Academy) under the auspices of French Jesuits. Its focus was to train translators to improve dialogue between traditional Chinese ideas and language and the ideas of Western modernity. Disagreements developed between Ma and the French Jesuits. They contended that Ma's pedagogical method and the resulting school atmosphere was chaotic. The vice director of the school sought to require top-down control of the curriculum and a French Université ethos. During the 1904-1905 academic year, the vice director alleged that Ma harbored revolutionaries at the university and abolished the student's self-governing body; Ma resigned.

Between 1912 and 1917, Ma and Ying Lianzhi petitioned the Holy See to establish an officially Catholic university in the capital of China's new republic. This helped bring about the founding of Catholic University of Peking, which was the only pontifical institution in China and the only Christian institution launched with an all-Chinese faculty.

Ma also founded the Fudan Public School (1905).
