Philip Wenman, 7th Viscount Wenman (18 April 1742 – 26 March 1800), styled The Honourable Philip Wenman until 1760, was a British landowner and politician.
Wenman was the son of Philip Wenman, 6th Viscount Wenman, by Sophia, eldest daughter and co-heir of James Herbert, of Tythorpe, Oxfordshire. Thomas Wenman was his younger brother. In 1760, aged 18, he succeeded in the viscountcy on the early death of his father. This was an Irish peerage and did not entitle him to a seat in the English House of Lords. In 1768 he was instead returned to the British House of Commons as a Knight of the Shire for Oxfordshire, a seat he held for the next 28 years.
Lord Wenman married Lady Eleanor, fifth daughter of Willoughby Bertie, 3rd Earl of Abingdon, in 1766. He died in March 1800, aged 57, when the viscountcy became extinct.
