John Bateman, 2nd Viscount Bateman (April 1721 – 2 March 1802) was a British politician.
In December 1744 he succeeded as second Viscount Bateman.
As the viscountcy was in the Peerage of Ireland, it did not disqualify him for election to the House of Commons of Great Britain. Lord Bateman was elected to Parliament for Orford on 31 January 1746, sitting until the general election of 1747. He was then elected for on 29 June 1747, being re-elected in 1754 and 1761. On 16 March 1768, during the general election of that year, Bateman was elected for Leominster. He was returned again in 1774 and 1780, but left the House at the 1784 general election.
Lord Bateman was made Lord Lieutenant of Herefordshire in 1747, holding the post until his death. On 19 November 1756 he was appointed to the Privy Council. Resident at Shobdon Court he was responsible for the complete rebuilding of St John's Church between 1849-52.
On his death at the age of eighty, the viscountcy became extinct. The Bateman title was later revived for William Hanbury, who was created Baron Bateman in 1837 and adopted the surname of Bateman-Hanbury.
