The Thailand Open (also known as PTT Pattaya Open) was a women's tennis tournament held in Pattaya, Thailand. Held since 1991, this WTA Tour event was classified as an International tournament and was played on hardcourts.

The event was part of the Tier V series from 1991 to 1992 and then again from 2001 to 2003. It was a Tier IV event from 1993 to 2000 and was promoted back to Tier IV in 2005, after a year's hiatus. Starting in 2009, the tournament became an International Series event. The 2015 PTT Thailand Open was the last edition.

Daniela Hantuchová holds the record for the most singles titles won with three: 2011, a successful title defence in 2012, and 2015.
