Thomas Robert Lavery (1852–1938) was an Irish Unionist (and later Northern Irish Unionist) politician. He worked as a director of a hemstitching company before his election as an Ulster Unionist Party member of Down County Council.
He served as Deputy Lieutenant of County Down. At the 1921 Northern Ireland general election, he was elected in Down,[1] and he held his seat, unopposed, at the 1925 general election. He stood down in 1929, due to illness, but was nonetheless elected the following year to the Senate of Northern Ireland, serving until his death in 1938.[2]
