Johan Natanael Törnros, known as Nabot (2 June 1878, Stockholm - by 1914, Hjo?) was a Swedish painter, illustrator and cartoonist.
He specialized in portraits and interiors.
After 1900, he was a member of a short-lived progressive artists' group known as "De Frie", which was notable for its inclusion of a female artist, Harriet Sundström.
His nickname is derived from the French word for dwarf.
