Ms Chu tied the knot in a small ceremony yesterday.
Hazel Chu, the Lord Mayor of Dublin, married her partner Patrick Costello, a Green Party TD, at a ceremony in the Mansion House over the weekend.
Last night, Chu took to social media to share a wedding photo, and to thank members of the public for their support.
"One Mrs, one Mr and a Mini!" she wrote.
"Today I married my best friend. I also had the privilege to go outside and greet members of the public who wanted to meet the Lord Mayor.

"Well wishers who we didn't know coming to wish us well. It's a real honour to have such support, thank you all."
Last night, Costello shared a photo with his Twitter followers.
"Married this amazing woman today," he wrote. "Thank you for all the lovely messages. Wishing you all well from my family to yours."

On June 18, Chu announced that her wedding was on a long itinerary of weekend plans.
"Apart from LeCheile anti racism rally in Smithfield Square tomorrow (come join us) & Direct Provision event on Sunday I'm officially taking the weekend off to get married," she wrote.
"We've moved our reception party out to next year but on Sunday, we'll be doing a small blessing in the house."
When the Green Party politician was elected Lord Mayor last June, she made history as the first Irish-born person of Chinese descent to be elected to political office in Ireland.
Hazel Chu regularly uses her platform to speak out against racism and harassment.
Earlier this year, the Mayor shared that she feared for her daughter's safety after being subjected to racist abuse outside their home.
Following the incident, she reiterated the importance of calling out racism during an
interview with Claire Byrne.
She said: "This is why it's really important that people actually do call it out and try to address these issues now because I don't want my three-year-old to grow up and realise we're back in the exact same place as we were 20 years ago."
