The Kalasan inscription is an inscription dated 700 Saka (778 CE), discovered in Kalasan village, Sleman Regency, Yogyakarta, Indonesia. The inscription was written in Sanskrit with Pranagari script (Northern India). This is the first inscription discovered in Indonesia that mentioned the dynastic name of Sailendra as Sailendravamça.

The inscription mentioned Guru Sang Raja Sailendravamçatilaka (Teacher of the King, the Jewel of the Sailendra family) who succeeded in persuading Maharaja Tejapurnapana Panangkaran (in other part of the inscription also called Kariyana Panangkaran) to construct a holy building for (Bodhisattvadevi) Tara and also build a Vihara (monastery) for Buddhist monks from Sailendra family's realm. Panangkaran donated the Kalaça village to Sangha (Buddhist monastic community). The temple dedicated to Tara is identified as Kalasan temple.

The inscription now is displayed in the National Museum of Indonesia, Jakarta, under inventory number No. D.147.
