The 1994 Taylor state by-election was held on 5 November 1994 in the South Australian House of Assembly electorate of Taylor, centred on Paralowie in the northern suburbs of Adelaide. The by-election was triggered by the resignation of state Labor MHA and former premier, Lynn Arnold, on 21 September 1994. The newly created seat had been won by Arnold at the 1993 state election with a primary vote of 51.06 percent.
The Liberal Party and the Democrats, who contested the previous election and gained 36.62 percent and 12.32 percent of the vote respectively, did not run candidates in the by-election. Labor easily retained the seat.
