Both Dershowitz, 81, and Starr, 73, were also recruited to defend convicted sex offender Jeffrey Epstein.
Dershowitz has been accused by one of Epstein's alleged victims of having had under-age sex with her.
He was also on the defense team of Harvey Weinstein.
The most surprising appointment though is Starr, who spent years trying to unseat President Bill Clinton, and was ultimately successful in forcing an impeachment trial which did not result in the former president's removal. While the House of Representatives voted to impeach Clinton, the Senate acquitted him.
One person who was very critical of Starr's performance in the proceedings describing him at the time as a "lunatic, and a "disaster," was in fact Mr Trump. "I really think Ken Starr was terrible," he said at the time.
A third lawyer, Robert Ray, 59, who replaced Starr as Special Prosecutor in September 1998, and led the prosecution in the Senate impeachment trial against Clinton, has also been lined up top defend Mr Trump. Mr Ray in 2006 was arrested for stalking a 'former companion,' who was aged 40.
All three of the new defense team, Starr, Dershowitz and Ray are regular contributors to the Fox News Channel.
White House counsel Pat Cipollone is heading Mr Trump's legal team, which also includes his personal lawyer Jay Sekulow.
Monica Lewinsky, a White House intern had sex with Clinton and told a friend, who recorded the conversation, and then exposed it. Starr switched his investigation from what was known as the White Water affair, to the sex allegations. The impeachment was not ultimately about the sex, but the fact that then-President Clinton lied about it.
Lewinsky was somewhat startled at Friday's news, tweeting: This is definitely an 'are you f.....g kidding me?' kinda day."
Starr was a Fox News contributor until Friday, however the channel told The Daily Beast on Friday he was no longer employed by the channel.
Both he and Dershowitz have been regulars on Fox News programs, with The Daily Beast saying the pair, together with Ray, have made roughly 300 appearances on Fox News in the past 12 months. The publication quoted the numbers from monitoring carried out by Media Matters for America.
