We present arguments for the existence of self-dual Yang-Mills
instantons for several spherically symmetric backgrounds with
Euclidean signature. The time-independent Yang-Mills field has
finite action and a vanishing energy momentum tensor and does not
disturb the geometry. We conjecture the existence of similar
solutions for any nonextremal 
-spherically symmetric
background.
