In molecules with more than one bond, both shape and bond polarity determine whether or not the molecule is polar. A molecule must contain polar bonds in order for the molecule to be polar, but if the polar bonds are aligned exactly opposite to each other, or if they are sufficiently symmetric, the bond polarities cancel out, making the molecule nonpolar.

Some molecules have positive and negative ends too, and when they do, we call them polar. If they don't, we call them non-polar. Things that are polar can.
