Suzanne Murphy — the hedge-fund exec who claimed she was threatened by her ex-husband’s young Polish wife — has won a round in her bitter custody battle with investment banker Robert B. Albertson, 67.

A judge ruled this month that Sandler O’Neill chief strategist Albertson’s new wife Karolina, 28, is not allowed around his and Murphy’s young daughter after Karolina’s arrest on second-degree ­aggravated-harassment charges for allegedly telling Murphy, “If you don’t leave my husband alone, I’m going to have your face smashed in.”

Karolina, who allegedly made threatening calls to Murphy in March, was previously ­ordered to stay away from Murphy, 46, for six months.

Albertson’s lawyer, Jeffrey Cohen, said, “We strongly disagree with the court’s ruling and our client fully intends to proceed with an appeal.”

Murphy had no comment. Out of court, Murphy got support from Gayle King.

After King sat by Murphy at a March of Dimes Spirit of Beauty Luncheon this month, King told the crowd, “I’m on team Suzanne all the way!”
