I assume you're talking about burning a candle. Nope, it's a chemical change. Candle wax is a chemical, and when you burn the candle, the wax reacts with oxygen in the air to produce carbon dioxide and water vapor (neither of which you can see.) Any smoke you see if simply soot from the burning of the wick.
(Looking a little deeper, wax, or paraffin, is a covalently bonded hydrocarbon alkane with the approximate formula C25H52. When it reacts with oxygen in a combustion reaction, the balanced equation for it is: C25H52 + 38O2 --> 25CO2 + 26H2O.)
