Pogatetz joined Columbus Crew on a free transfer from Nurnberg in summer 2014, and his contract expired after last season, which saw the Crew reach the final against Portland.
However, the former Middlesbrough defender did not feature after suffering a knee injury in September last year.
Pogatetz, who made 110 Premier League appearances as well as featuring in 88 Bundesliga matches for Hannover, Wolfsburg and Nurnberg, signed his short-term contract, which includes an option for another year, at the Bundesliga II side on Tuesday.
"I am looking forward to this new challenge," the Austrian said.
"He's shown leader qualities in both Premier League and Bundesliga," Union coach Sascha Lewandowski said. "He's certainly capable of providing stability."
After 19 matches this season, Union Berlin, who started the year with high hopes, are 13th in Bundesliga II. United States international Bobby Wood is the club's top scorer with seven goals.
