They're very different.
Curve-fitting is when you have a dataset of scattered points and find a line (or curve) that best fits the general shape of the data.
Interpolation is when you have two points of data and want to know what a value between the two would be. Half way between would be their average, but if you want to know only a quarter of the way between the two you'd have to interpolate.

Curve fitting is finding a general curve (function) which best fits a series of points.
Interpolation is finding a value given two points.
