1026 Ingrid, provisional designation 1923 NY, is a stony Florian asteroid and long-lost minor planet (1923–1986) from the inner regions of the asteroid belt, approximately 7 kilometers in diameter. It was discovered by Karl Reinmuth at Heidelberg in 1923, and later named after Ingrid, niece and godchild of astronomer Albrecht Kahrstedt.^[10]
