# Ade Chandra

Ade Chandra (Chinese: 張鑫源; born 4 February 1950) is an Indonesian retired badminton player.

## Career

A doubles specialist of ample bulk by Indonesian standards, he was noted for his power and quick defensive reflexes. With the formidable Christian Hadinata he won numerous international men's doubles titles between 1972 and 1980, including a pair of All-England titles, though they were often runners-up to fellow countrymen Tjun Tjun and Johan Wahjudi at major events . They were unbeaten in two Thomas Cup campaigns together (1973, 1976) both of which resulted in world team titles for Indonesia. Late in Chandra's career he won men's doubles with Christian at the 1980 IBF World Championships in Jakarta.
