Well, if you are talking about the US: Federal law trumps state laws.
However, there are limits on federal law: It can only cover specific areas, such as interstate commerce (what that exactly means is a topic of frequent debate, but is used to justify federal anti-drug laws and environmental regulations).
Congress CAN, however, "encourage" states by way of economic incentives (e.g. transportation fund) to behave in certain ways.
