Sang Pencerah (The Enlightener) is a 2010 Indonesian film directed by Hanung Bramantyo and starring Lukman Sardi, Zaskia Adya Mecca, and Slamet Rahardjo. It is a biopic of Ahmad Dahlan which describes how he came to found the Islamic organisation Muhammadiyah.

Sang Pencerah, produced to coincide with Muhammadiyah's centenary, was announced in November 2009. It was meant to be historically accurate, with much of the Rp. 12 billion (US$1.3 million) budget paying for period costumes and sets. However, as documentation on the early years of Dahlan's life is lacking, those scenes were fictionalised. Sang Pencerah marks the feature film debut of Ihsan Tarore and Giring Ganesha.

The film, released on 8 September 2010 during the Eid ul-Fitr holiday, was meant to show different views of Islam; however, it has also been interpreted as a critique of the current Muhammadiyah leadership. It was seen in theatres by over 1 million people – the only Indonesian film of 2010 to do so. It also received favourable critical reception, winning the 2011 Bandung Film Festival after being refused a nomination at the 2010 Indonesian Film Festival. However, some Muslim critics decried it as being too liberal.
