Mount Popa (Burmese: ပုပ္ပားတောင်; MLCTS: puppa: taung, IPA: [pòpá tàʊɴ]) is a volcano 1518 metres (4981 feet) above sea level, and located in central Burma (Myanmar) about 50 km (31 mi) southeast of Bagan (alt: Pagan) in the Pegu Range. It can be seen from the River Ayeyarwady (Irrawaddy) as far away as 60 km (37 mi) in clear weather. Mount Popa is perhaps best known for the nearby stunningly picturesque Popa Taungkalat monastery atop an outcrop. The Popa Taungkalat (Taung Kalat) Shrine is home to 37 Mahagiri Nats, or spirits. Statues depicting the Nats are at the base of the Shrine.

The name Popa is believed to come from the Pali Sanskrit word 'popa' meaning flower.

The main edifice of the volcano is composed of basalt and basaltic andesite lava flows, along with pyroclastic deposits and scoriaceous material, originating from strombolian eruptions which are thought to have made up the later stages of the volcano's growth. The volcano also contains a 1.6 km (0.99 mi) wide and 0.85 km (0.53 mi) deep caldera that is breached to the northwest and is thought to have formed due to failure of the volcano's slopes. A 3 km³ (0.72 cu mi) debris avalanche can be found to the north of the caldera's breach. It covers an area of 27 km² (10 sq mi).
