Star-forming regions are among the richest chemical environments in the universe, where atoms and simple molecules evolve into complex organic species under the influence of diverse physical processes. From cold pre-stellar cores to the birth of protostars and their surrounding disks, chemistry traces the evolution of matter and plays a key role in setting the initial conditions for planet formation. In this talk, I will review our current understanding of interstellar chemistry across different types of star-forming regions and evolutionary stages, with a particular emphasis on the interplay between gas-phase and grain-surface processes. I will present recent insights from observational surveys and astrochemical modeling, highlighting key molecular tracers of the physical history and evolution of star-forming regions. By bridging chemical models with multi-wavelength observations, we are beginning to uncover the origins of chemical diversity among star-forming regions and its implications for the molecular inventory of nascent planetary systems.
