Answer is: the anode.
An electrochemical cell (galvanic cell) is generating electrical energy from chemical reactions.
In galvanic cell specie(for example zinc and zinc cations) from one half-cell lose electrons (oxidation) and species from the other half-cell (for example copper and copper cations) gain electrons (reduction).
Oxidation on zinc anode: Zn(s) → Zn²⁺(aq) + 2e⁻.

The location of oxidation in an electrochemical cell: the anode
Further explanation
Voltaic cells or also called galvanic cells are electrochemical cells that produce electrical energy due to redoxs reactions / chemical reactions.
Electric current is generated due to the flow of electrons from the anode that undergoes an oxidation reaction to the cathode which has a reduction reaction in the circuit of an outer wire circuit
The parts of a voltaic cell are:
- Cathode : reduction occurs, a positive pole
- Anode: oxidation occurs, a negative pole
- Electrolytes: an electrically conductive solution on both electrodes
- Conductor wire: the link between the cathode and the anode
- Salt bridge: as neutralizing anions and excess cations of electrolyte solution (supplying anions to the anode and cations to the cathode; for example KNO₃ solution)
In the electrolytic cell the positive pole - the anode whereas the negative pole - the cathode
Both of these electrochemical cells (volataic cell and electrolytic cell) still show that oxidation reactions occur at the anode despite different signs
