Arthur Coggshall Weaver (April 7, 1879 – March 23, 1917) was a Major League Baseball player. He was born in Wichita, Kansas, and died in Denver, Colorado. Weaver played for four teams from 1902 to 1908, playing most of his games at catcher.
Asthma-related complications brought Weaver's career to a premature end, and contributed to his early death at the age of 37.
