The 2005–06 season of Hereford United F.C. was the 9th season in the Conference. All the members of the squad were signed on free transfers, in keeping with previous squads. Hereford finished second in the league for the third season running and, unlike the previous seasons, progressed to the play-off final. A 3–2 extra-time victory over Halifax Town secured promotion back to the Football League after a nine-year spell in non-league football. This season saw the emergence of Andy Williams, a product of the youth system at Hereford.
