真空感应熔炼（Vacuum induction melting，简称VIM）是一种在真空条件下利用电磁感应加热原理来熔炼金属的金属工艺制程。在电磁感应过程中会产生涡电流，使金属熔化。此制程可用来提炼高纯度的金属及合金。

Vacuum induction melting (VIM) utilizes electric currents to melt metal within a vacuum. The first prototype was developed in 1920. One of the only ways to induce a current within a conductor is through electromagnetic induction. Electromagnetic induction induces eddy currents within conductors by changing the magnetic field. Eddy currents create heating effects to melt the metal. Vacuum induction melting has been used in both the aerospace and nuclear industries.
