  The search for artificial topological superconductivity has been limited by
the stringent conditions required for its emergence. As exemplified by the
recent discoveries of various correlated electronic states in twisted van der
Waals materials, moir\'e patterns can act as a powerful knob to create
artificial electronic structures. Here, we demonstrate that a moir\'e pattern
between a van der Waals superconductor and a monolayer ferromagnet creates a
periodic potential modulation that enables the realization of a topological
superconducting state that would not be accessible in the absence of the
moir\'e. The magnetic moir\'e pattern gives rise to Yu-Shiba-Rusinov minibands
and periodic modulation of the Majorana edge modes that we detect using
low-temperature scanning tunneling microscopy (STM) and spectroscopy (STS).
Moir\'e patterns and, more broadly, periodic potential modulations are powerful
tools to overcome the conventional constrains for realizing and controlling
topological superconductivity.
