Waller Bacon (c. 1669 – 1734), of Earlham Hall, near Norwich, was a British lawyer and Whig politician who sat in the House of Commons for 24 years between 1705 and 1734.
At the 1705 English general election, he stood at Norwich on the Whig interest with the backing of Lord Townshend, but there was a double return, and he was not seated as Member of Parliament until 6 December 1705.
In January 1706 he was on a committee to draft a bill to regulate duties on coal imports into Great Yarmouth, following popular pressure from Norwich and Norfolk..
In February he reported a petition of some army officers for relief and was ordered to bring in a bill to this end.
In December, he was appointed to draft another bill on Yarmouth coal duties, which he brought successfully through the House.
In February 1707 he reported another petition of army officers for arrears of pay, and introduced a bill in March to state the accounts of the regiments concerned.
In 1721, following petitions from wool manufacturers, including those of Norwich, he introduced a bill, which became law, to prohibit wearing calico.
