Jamison Dean "Jamey" Newberg (born March 3, 1969) is a Dallas, Texas lawyer and sports writer who became fairly well known since the late 1990s as an expert multi-media commentator on the Texas Rangers baseball organization, with an emphasis on the subtleties of minor league player development and complex trade strategies.

[3] As of February 2018, Newberg joined subscription-based sports website The Athletic as a contributing writer covering the Texas Rangers.

[8] Newberg's independence and impartiality were called into question during the Rangers 2010 bankruptcy proceedings, when the Dallas Morning News revealed that the organization had paid Newberg in excess of $27,000, in addition to paying for him and his family to attend the team's spring training in Arizona.

[9] Newberg maintained that his "obnoxious optimism" regarding the Rangers is genuine and not a condition for compensation from the organization, and said that the payments he received were for content he produced for the Rangers' website, gameday programs, and books he'd written that were distributed by the team to season ticket holders.

[10] Craig Calcaterra of NBC Sports was critical of Newberg, saying that he should have previously disclosed his financial arrangement with the Rangers to his readers.
