Count Soejima Taneomi (副島 種臣, October 17, 1828 – January 31, 1905) was a diplomat and statesman during early Meiji period Japan.

While most of Japan's government was on its around-the-world tour of the United States and Europe on the Iwakura Mission, Soejima served as interim Foreign Minister.

[1] In 1873, Soejima led a mission to Beijing to protest the murder of 54 crewmembers of a wrecked Ryūkyūan merchant vessel by Paiwan aborigines on the southwestern tip of Taiwan in December 1871.

Soejima succeeded in meeting with the Tongzhi Emperor partly on the basis of the goodwill extended over the Maria Luz Incident, but Japan's demands for compensation were refused, leading to the Taiwan Expedition of 1874.

After the return of the Iwakura Mission and the rejection of the Seikanron proposals to invade Korea in October 1873, Soejima resigned from the government.
