Nicholas (Nikolaus) Mercator (s. 1620, Holstein – 1687, Versailles), juga dikenal dengan nama Jermanik Kauffmann, adalah seorang matematikawan abad ke-17. Ia lahir di Eutin, Schleswig-Holstein, Jerman dan dididik di Rostock dan Leyden. Setelah itu, ia menetap di Belanda dari 1642 sampai 1648. Ia mengajar di Universitas Kopenhagen pada 1648–1654 dan menetap di Paris dari 1655 sampai 1657.
Dalam bidang matematika, ia dikenal karena membuat risalah berjudul Logarithmo-technia tentang logaritma, terbitan tahun 1668. Dalam risalah tersebut, ia mendeskripsikan seri Mercator, yang juga ditemukan secara terpisah oleh Gregory Saint-Vincent:
