Ing Chang-Ki (Traditional Chinese: 應昌期, Simplified Chinese: 应昌期, Hanyu Pinyin: Ying Changqi (Yžng Chāngqī), born October 23, 1917, died August 27, 1997) was a Chinese millionaire industrialist of Taiwan who learned to play Go when eight years old, and spent his lifetime promoting the game. Ing died at the age of 79.
- He devised a proper set of rules: the Ing Rules -- simple enough for pre-school age children (except maybe for the ko rules)
- He also devised playing equipment (see Ing stones) and donated much of it to Go federations worldwide
- He proposed to change the name of the game in English to "Goe".
- Founded the Ing Chang-Ki Wei-Ch'i Educational Foundation in 1983, which continues his work even after his death, including (partially) funding the Ing Cup.
- Founded the Ing Prize in computer Go
