Thomas Forrester (1790 – November 15, 1841) was a merchant and political figure in Nova Scotia.
He represented Halifax township in the Nova Scotia House of Assembly from 1836 to 1841 as a Reformer.
Originally a supporter of Joseph Howe, Forrester later withdrew his support because he felt that Howe had made too many compromises to become part of the coalition government.
During the financial crisis of 1837, Forrester sued the Bank of Nova Scotia for refusing to redeem paper money for coin.
He died in office in Halifax after suffering from poor health for several months.
