Christopher John Wilder (born 23 September 1967) is an English professional football manager who formerly played as a right-back.

In December 1987, defender Wilder was sent off for a crude tackle on Millwall's Jimmy Carter in a season which saw the Sheffield club relegated to the third division.

Wilder's first full season in charge of Oxford began successfully and by mid-season they were top of the Conference table by five points with a game in hand.

However, Oxford were overtaken by Stevenage, who would go on to win the title and take the automatic promotion place, consigning the Us to the playoffs with Luton Town, Rushden & Diamonds and York City.

They defeated Rushden & Diamonds to reach the play-off final, and gained promotion to the Football League by beating York City 3–1.
