Batu bara adalah salah satu bahan bakar fosil. Pengertian umumnya adalah batuan sedimen yang dapat terbakar, terbentuk dari endapan organik, utamanya adalah sisa-sisa tumbuhan dan terbentuk melalui proses pembatubaraan. Unsur-unsur utamanya terdiri dari karbon, hidrogen dan nitrogen dan oksigen
Batu bara juga adalah batuan organik yang memiliki sifat-sifat fisika dan kimia yang kompleks yang dapat ditemui dalam berbagai bentuk.
