Larry Seidlin (born May 24, 1950 in The Bronx, New York) was a State Court judge for the Circuit Court of the Seventeenth Judicial Circuit of the State of Florida in and for Broward County. He was the presiding judge during the infamous Anna Nicole Smith body custody hearing after her death.

As judge during the Anna Nicole Smith body custody hearing, Judge Seidlin was involved in some controversial actions, such as making one-liners and other attempts at humor which some who know him said is normal for him, but led many to speculate that his actions and comments were for the cameras in the courtroom and were made as an attempt to secure a courtroom television show similar to Judge Judy's. The judgment was given in what some have viewed as an overly theatrical style, with the Judge weeping and fumbling his words, though others close to him have said that his courtroom conduct was genuine.

However, South Florida lawyers advise that Seidlin has always been a bit of a comical judge. His courtroom antics serve to relax the participants in the process. In juvenile cases, he has been known to give "stern warnings" where appropriate. Seidlin has come under fire for giving his friends all public appointments for which they get several hundred dollars apiece. However, this is commonplace among Broward County attorneys. Currently the law has changed and there is a wheel system wherein judges have no discretion to appoint attorneys of their choice.
