I Am a Singer is the fourth season of the Chinese version of the South Korean reality show I Am a Singer. The show was broadcast on Hunan Television in 2016. Due to the sudden banning of Korean entertainment in China in November 2016, this was currently the last season to feature Korean singers in the competition. It was also the last season to use the I Am a Singer title, before renaming to Singer with effect from the next season.

The season premiered on 15 January 2016, and concluded on 15 April 2016. On the finals aired 8 April 2016, Hong Kong-American singer Coco Lee was the winner of the season, becoming the first non-mainland Chinese national to win the show. Jeff Chang came in second, and Korean singer Hwang Chi-yeul finished third place.

Competition format Most of the competition followed the same format as the previous series, including the Challenge rounds debuted in the last season. Like the previous seasons, the votes counted from both the Qualifier and Knockout rounds determined which singer was eliminated for the night. The Challenge round which introduced in the previous season also return, with an added rule where singers had to rank in the top four (4th place or better) to remain in the competition.

I Am a Singer- Who Will Challenge An online Spin-off of the show, I Am a Singer- Who Will Challenge (我是歌手—誰來踢館) was aired daily from 5 December 2015, until the finale on 23 January 2016, on the online site of Mango TV, for a total of 50 days.

The site featured each contestant having their own Challenge page, where online viewers were able recommend the singers in participating the competition. When a singer's recommendation hit at least 18,000 views, they were eligible to participate in a daily live show aired between 5 December 2015, until 7 January 2016. During each episode's broadcast, viewers could distribute their 100 "Decibel points" to the singers they liked the most on each show.

The top eight singers accumulating the most 'Decibel points' after 7 January moved on to the Sing-off. During each night's broadcast until 15 January, two random singers had to sing one song each, with a total of three songs throughout the eight shows. 10,000 viewers were chosen at random. These viewers distributed their 100 "Decibel points" to determine the contestants placement in the sing-off as well as in the finale. The second week's shows that aired from 16 January until 22 January featured the singer's daily lives and their preparations up to the finale.

The finale aired 23 January and showcased the eight singers for the last time, each singing two songs (one chosen song and one hit song from previous seasons). In each round, 10,000 "Decibel points were distributed to random viewers eligible to cast their votes for the winner (viewers had to vote for three singers to be counted as a valid vote). The singer accumulating the most votes after two songs would win the right to take part in the competition as a Challenger on the third Challenge round.

Korean singer Kim Ji-Mun was named as the winner of I Am a Singer- Who Will Challenge.

Tiebreaker A tiebreaker can occur when multiple singers were tied with the lowest votes cast during an elimination round. The tie is resolved based on the placements in the next round, and the singer receiving a lower placement (regardless of the placements from other singers) was eliminated. Any eliminations (if applicable) in the following round would conduct as normal.
