**Abstract**

Corrosion of metals and its alloys destroys our properties, our environment, and our lives. Thus, corrosion control includes a range of developed treatments that take into account material properties, environmental characteristics, and process cost. Typical corrosion inhibitors are known for their excellent efficiency and show great promise. However, they become less used because they cause serious toxicity issues on the environment and affect human and animal health. In recent years, research has intensified on the development of green chemistry technologies, which offer new methods of synthesis and extraction of various non-toxic materials (plant extracts, oils, amino acids, rare earths, etc.), which are highly effective, environmentally acceptable, economical and easily available inhibitors. This chapter deals with a description of corrosion inhibitors with a particular emphasis given to the discussion on the different characteristic features of the green corrosion inhibitors reported in the literature as a comparative view of toxic inhibitors.
