They're calling it "Married To Equality."
The celebration comes after the ban on same sex marriage in Arkansas was lifted for a short time in May of this year.
Five hundred same-sex couples received marriage licenses in the Natural State.
Event Director Michael Walsh says the the reception celebrates the historic event.
"In addition to being the first city in Arkansas where gay people could get married, we're the first city in Arkansas to throw them a wedding reception," Walsh said.
Several "guests of honor" were on hand, including Jennifer Rambo and her partner Kristin Seaton.
They were the first couple issued a license in the state.
The National Human Rights Campaign and the Eureka Springs Gay Business Guild sponsored the reception.
More than 40 restaurants, hotels, gift shops, galleries and retailers contributed to the event.
