The National Athletic and Cycling Association (NACA or N.A. and C.A.), from 1990 the National Athletic and Cycling Association of Ireland (NACAI or NACA(I))[1] was a federation of sports clubs in the island of Ireland practising athletics or bicycle racing or both. It existed from 1922 to 2000, though for most of the period it was not the sole governing body in Ireland for either sport. Its refusal to recognise the partition of Ireland got it expelled from the International Amateur Athletics Federation (IAAF) and the Union Cycliste Internationale (UCI). Clubs formerly in the NACAI are now affiliated to Athletics Ireland or Cycling Ireland, each formed by the merger of the NACAI with rival bodies respectively affiliated to the IAAF and the UCI.
