Ross County substitute Neal Hooks nodded the winner to see off Queen of the South in the First Division basement battle.
Hooks' looping header put the home side in front in the 33rd minute. John O'Neill had Queen's best chances but was wasteful in front of goal.
County should have increased their lead, but Queens keeper Craig Hinchcliffe was in inspirational form.
With 15 minutes left, Martin Scott saw red for after stamping on Neil Scally.
