Walter Newton Justis (August 17, 1883 – October 4, 1941), nicknamed "Smoke", was a Major League Baseball pitcher who played in 1905 with the Detroit Tigers.

He spent several years playing professional ball in various minor leagues.

In 1908, he set a still-standing minor league record by pitching four no-hitters for the Lancaster Lanks.

In 1913, his last season, he famously threw a shutout to win the home opener for the premiere season of the Covington Blue Sox at Federal Park (two blocks from where a sports bar now carries his namesake).
