Nicolas Sarrabat or Sarabat (February 7, 1698 – April 27, 1739), also known as Nicolas Sarrabat de la Baisse, was an eighteenth-century French mathematician and scientist.
He was born in Lyon, the son of the painter Daniel Sarrabat (1666–1748), and the nephew of engraver Isaac Sarrabat.
The Sarrabats had been a prosperous Protestant bourgeois family of clock- and watchmakers, though Nicolas's father had converted to Catholicism.
Sarrabat showed a love of learning from an early age.
