Dina Lohan (born Donata Sullivan on September 15, 1962 in New York) is a television personality who rose to fame as the mother and manager of actress/pop singer Lindsay Lohan, and Lindsay's younger sister Ali Lohan, with whom Dina co-stars in the reality show Living Lohan.

Dina and her younger daughter Ali began a reality show, Living Lohan, which debuted on May 26, 2008 on the cable television network E!. Dina is also one of the executive producers of the series.

Lohan has been the subject of media scrutiny for making her daughter Ali the star of a reality television program, and for her regard to daughter Lindsay's recovery from drug and alcohol abuse. She has responded to the latter matter by insisting that Lindsay's problems were not her fault, nor those of Lindsay's friends, but were the result of personal choices, for which Lindsay would have to take responsibility, and that Lindsay was in the process of rebuilding her life. She has also been accused of capitalizing on Lindsay's fame and personal struggles in order to launch her own career, having been criticized for bringing cameramen from the entertainment newsmagazine series Entertainment Tonight to film her visiting Lindsay in drug rehabilitation, to the ire of her daughter and the facility staff.
