There are some confused answers here. The anode is not necessarily always negative — neither is the cathode always positive (exceptions are in non-spontaneous reactions). However, the anode is always oxidation and the cathode is always reduction, so then the electrons flow from anode to cathode.
It always goes from the anode to the cathode in a Galvanic cell since the anode is negatively charged and the cathode is positively charged and will attract the electrons from the anode. However, in an electrolytic cell, the cathode and anode do not have the same charges, regardless the electron still flows from the anode to the cathode.
