Sir John Brownlow, 1st Baronet (c. 1594–24 November 1679) of Belton, near Grantham in Lincolnshire, was twice Sheriff of Lincolnshire and on 26 July 1641 was created a baronet "of Belton in the County of Lincoln". He died without progeny when his baronetcy became extinct. His monument survives in Belton Church, showing half statues of himself and his wife finely sculpted in white marble.
