William E. Baxter, Jr. (born 21 september, 1940) is an American professional poker player and sports bettor.

In 1975, Baxter took a honeymoon trip to Hawaii and ended up in the Las Vegas Valley, Nevada on the way back.

It was there that he met fellow legends Doyle Brunson, Puggy Pearson and eventually Stu Ungar.

Baxter won an Ace-to-Five Lowball event at the 1981 Super Bowl of Poker.

Thus, in the process, Baxter's victory in this case has helped all American poker players by providing equal tax status to those earning a living as professional poker players.
