According to LTV around 200 people, mainly but not exclusively female, took part in the peaceful parade through central Riga.
Displaying a range of imaginative signs in various languages, the stated aim of the event was to draw attention to potential threats to women's rights in coming years, following widely-reported lewd and misogynistic bragging about sexual assault by the new leader of the free world.
"I personally do not want to face a situation where women are valued only by their appearance or as politicians' wives and the rhetoric in the media is mainly associated with how they look or how they have behaved, not by their intellectual potential," said walk participant Liena Jurgelāne.
Many participants sported pink hats and the crowd was good-natured with no trouble reported.
Another participant, Iveta Ivansone, said she had grown up in the United States but now lives in Latvia.
"For me it is beyond belief that today in Riga I have to take action on human rights in America, against Trump," she said.
Around 600 similar events are reporte to have taken place around the world January 21.
