琥珀酸（IUPAC中文名稱為丁二酸；傳統認為它是琥珀的精髓）是一種二羧酸，化學式为HOOC–CH2–CH2–COOH。 在常溫的情況下，純琥珀酸是固體，呈無色無味的晶体。它的熔點及沸點分別是185°C及235°C。它形成的陰離子稱為琥珀酸根离子，是三羧酸循環其中的一分子，且是能夠在以下化學反應中放出電子予電子傳遞鏈： 琥珀酸鹽 + 黃素腺嘌呤二核苷酸 → + FADH2 這個過程由琥珀酸脫氫酶（或是由粒線體電子傳遞鏈中的複合物II）所催化。該複合物是4亞單位膜結合脂蛋白，配合琥珀酸的氧化作用及泛醌的還原作用。中介電子載體為黃素腺嘌呤二核苷酸及3個B亞單位Fe2S2群集部份。 琥珀酸的酯稱為琥珀酸酯。
