Baron Brownlow, of Belton in the County of Lincoln, is a title in the Peerage of Great Britain. It was created in 1776 for Sir Brownlow Cust, 4th Baronet.

His son Brownlow Cust, 4th Baronet represented Ilchester, Somerset, and Grantham in Parliament and in 1776 was raised to the peerage as Baron Brownlow, "of Belton in the County of Lincoln", chiefly in recognition of his father's services.
