Sir Joseph Lawrence (23 September 1848 – 24 October 1919) was a Conservative Party politician in the United Kingdom.
He was elected as Member of Parliament (MP) for Monmouth Boroughs at by-election in May 1901. The by-election was triggered by the unseating of the Conservative victor of the seat at the general election in October 1900, Dr Frederick Rutherfoord Harris, as a result of an election petition alleging irregularities in election spending.
The Conservative majority at the by-election was half that of the previous year, and Lawrence did not stand for re-election in 1906, when the seat was won by the Liberal Party candidate.
Lawrence was knighted in the 1902 Coronation Honours.
