Robert Cahaly is an American pollster and founder of the Trafalgar Group. He was previously a political consultant for Republican Party candidates.

Cahaly founded Trafalgar Group in 2016. He drew attention in the aftermath of the election, in which Trafalgar had been one of the only polling firms to predict Donald Trump's victory over Hillary Clinton in the 2016 presidential election. Cahaly claimed that Trafalgar's polling methodology had more accurate than other polls because it utilizes methods to increase the weighting of so-called "shy, pro-Trump" voters which they argue to be underrepresented in most polls. Cahaly does not disclose Trafalgar's group's methods of polling or its process for ascertaining the volume of shy Trump voters in the electorate.

Leading up to the 2020 presidential election, Cahaly garnered substantial media attention for his emphatic assertions that Trump would prevail easily over Joe Biden in the 2020 election.

Cahaly has worked on campaigns for various Republicans, including governors Carroll Campbell, David Beasley, Mike Huckabee, Nikki Haley, Chris Christie, and Henry McMaster; US Senators Strom Thurmond, Bob Dole, Tim Scott, and Ben Sasse; and Presidents George H. W. Bush, George W. Bush, and Donald J. Trump.
