Daniel Tavernier (c. 1610 – September 10, 1648) was a French adventurer and merchant active in East Asia during the first half of the 17th century. He was born in Antwerp of a French or Flemish Huguenot family which subsequently returned to Paris after the publication of the Edict of Nantes, which promised protection for French Protestants. Daniel is an older brother of the more famous Jean-Baptiste Tavernier (1605 - 1689), who discovered the Tavernier Blue Diamond (Hope Diamond) and pioneered East Asian trade. Daniel is known to have made 11 or 12 voyages to Tonquin (North Vietnam) from Batavia in the Dutch East Indies. Having settled in the Dutch port of Batavia, he preceded Jean-Baptiste to East Asia by at least 10 years. Daniel's presence in Batavia probably inspired Jean-Baptiste to travel there on his second voyage. Daniel probably served as a guide for Jean-Baptiste on his voyage, which included a stop in Vietnam. Daniel Tavernier died in Batavia of dysentery on September 10 of 1648. He never published in his lifetime, but a map either drawn by him, or based upon his journals, was published by his brother, Jean-Baptiste, in 1679.
