A large room‐temperature magnetoelectric response is crucial for the practical application of magnetoelectric materials. However, such a response has never been achieved in molecular–ionic ferroelectric‐based laminated magnetoelectric composites. Herein, the laminated magnetoelectric composite of Metglas/ 1 ( 1 = [N(CH 3 ) 4 ][GaBrCl 3 ] and Metglas = an amorphous FeBSi alloy) is prepared by combining the molecular–ionic ferroelectric 1 with Metglas in the longitudinally magnetized and transversely poled (L–T) mode. The room‐temperature magnetoelectric response of the composite is up to 8.74 V Oe −1 cm −1 at the resonance frequency (≈45 kHz), representing the largest room‐temperature magnetoelectric response reported for the molecular–ionic ferroelectric‐based laminated magnetoelectric composites to date.
