William Alexander Parsons Martin (April 10, 1827 – December 17, 1916), also known as Ding Weiliang (Chinese: 丁韙良), was an American Presbyterian missionary to China and translator, famous for having translated a number of important Western treatises into Chinese, such as Henry Wheaton's Elements of International Law.

Martin was born in Livonia, Indiana. He graduated from Indiana University in 1846, known at that time as Indiana College, and then studied theology at the Presbyterian seminary, New Albany, Indiana. In 1850 Martin arrived in Ningbo, Zhejiang, China, where he worked for the next ten years.

Martin served as interpreter for the United States minister William B. Reed, in negotiating the treaty of Treaty of Tientsin in 1858 with China, and in 1859 traveled with his successor, John Elliot Ward, to Beijing and to Edo, Japan.

From 1863 till 1868, he worked at Beijing, often as official interpreter for the American Minister to China, Anson Burlingame. He was reputed to be the first foreigner to make the journey from Beijing to Shanghai on the Grand Canal of China, and described the trip in the "Journal of the Asiatic Society" (1866). In 1869, Martin became president of the Tongwenguan in Beijing until 1895, and a professor of international law. He acted as an adviser of Chinese officials on questions of international law when disputes arose with European powers, notably during the conflict with France in 1884–1885. In the same year he was made a mandarin of the third class.
