نيلس گابرييل سفستروم (Nils Gabriel Sefström ؛ 2 يونيو 1787 - 30 نوفمبر 1845) كان كيميائياً سويدياً. Sefström was a student of Berzelius and, when studying the brittleness of steel in 1830, he rediscovered a new chemical element, to which he gave the name vanadium.^[1]

Vanadium was first discovered by the Spanish-Mexican mineralogist Andrés Manuel del Río in 1801. He named it erythronium. Friedrich Wöhler later confirmed that vanadium and erythronium were the same substance.^[2]

Sefström was member of the Royal Swedish Academy of Sciences from 1815.

The Spitzbergen glacier Sefströmbreen,^[3] and the mountain ridge of Sefströmkammen, are named after him.^[4]
