2016 WTA 125K series

The WTA 125K series is the secondary professional tennis circuit organised by the Women's Tennis Association. The 2016 WTA 125K series calendar consists of eight tournaments, each with a total prize fund of $125,000. After 2015, the Nanchang event was upgraded to a WTA International level tournament, and with new events starting in San Antonio, West Hempstead and Bol. The planned tournament in West Hempstead was then cancelled, and the tournament scheduled to take place in Carlsbad, California was moved to Oahu, Hawaii. Following the death of the Thai king Bhumibol Abdulyadej, the event due to take place in Hua Hin was also cancelled, in accordance with Thai tradition that sporting events cannot take place in the month after a monarch's death.
