A by-election was held in the New South Wales state electoral district of Upper Hunter on 8 June 1918. The by-election was triggered by the resignation of Mac Abbott ().
Abbott had been re-elected on a pro-conscriptionist platform at the 1917 state election, despite his electorate voting "No" in the 1916 referendum on overseas service for conscripted soldiers. During his re-election campaign he publicly committed to resigning his seat if another "No" vote was returned at the repeat referendum in 1917. He kept his promise by resigning his seat on 10 May 1918 and returned to his legal practice.
