Sao Saw Et (Thai: เสาร์ซาวเอ็ด, lit: Saturday the 21st, in Northern Thai) was an incident of discrimination against LGBT people in Chiang Mai, Thailand, consisting of hate speech and violent attempts to stop the 2009 Pride Parade which was scheduled to take place there on 21 February 2009, ultimately leading to its cancellation.

Among the reasons given for the parade to be cancelled were that would "destroy the beautiful Lanna culture" or “cause the youth to imitate the [LGBT] behaviour".

[1] Local government officials, including the province governor and the head of cultural division, were inclined towards cancellation.

Moreover, local news agencies and radio stations at the time were reported to spread hate speech towards the LGBT participants and even incited the crowd to throw things and block the parade route.

The armed group, which reportedly consisted of a thousand people, put up banners and used speakers to curse at participants trapped inside the blockade.
