Logan started dating the New Zealand actress Anna Paquin in 2004, and they were together for around a year; he then dated the American actress Kelli Garner, but they broke up after a couple of months.
In 2008, Logan began dating Marisa Tomei, an Oscar-winning American actress with close to 100 credits to her name, and there were rumors circulating the internet in 2011, claiming that the two were engaged; they have both denied this, and in any case broke-up in 2012.
Logan married the Mexican-American actress Diane Gaeta in 2012, in a private ceremony attended by only the closest of their friends and family members. Diane gave birth to their son Tennessee Logan Marshall-Green in 2014, but she and Logan divorced on 23 July 2020, after she’d accused him of being unfaithful.
As of March 2022, Logan seems to be single, was once married to Diane Gaeta, and has a son with her.
