The event saw 20 couples have dinner at a farm, with intelligence suggesting the party was due to happen afterwards.
According to local media, police knocked on the door of the property at 10pm, which is about 400km south of Buenos Aires.
But when the officer arrived, they were surprised to be greeted and invited in.
Speaking to local media outlet Infobae, a police source said: "When they saw us they thought we were part of the show. That we were strippers."
When they were inside, one of the women who was taking part in the party ran into one of the officers, but, thinking he was there as entertainment, she reportedly whispered: "Look at your eyes. You warm me."
The operation was led by General Pueyrredón's Undersecretary of Security, Gustavo Jara, who said that the people involved were 'respectful, did not resist, and even joked about what happened'.
He added: "People didn't know what was going on. One of them, realising we weren't strippers, told us, 'Uh, we were excited.' It was comical and absurd at the same time."
It's not the first time the same mistake has been made.
Back in 2016, a police community support officer was mistaken for a stripper after he walked in on a 50th birthday party.
PCSO Mike Ober was patrolling the neighbourhood in a Wiltshire town when he spotted a social club had an open door.
He popped his head in and said he was greeted with 'wild excitement' by a group of women who thought he was there as a stripper.
As reported by the BBC, he said: "The party was about to get started and they thought I was early."
He added: "I had to beat a hasty retreat."
Ober, who was in his 20s, said: "There were no cars in the car park and the door was propped open.
"But as I went in there were loud cheers and someone shouted: 'Oh, are you the stripogram?'"
When he was told he was too early, he walked out, passing the actual stripper on the way in.
He said: "It's a matter of personal taste, but the uniforms aren't very flattering, so I guess [the mix-up] is flattering."
