Harry Todd (born John Nelson Todd; December 13, 1863 – February 15, 1935) was an American actor.

A native of Allegheny, Pennsylvania, Todd was one of at least five siblings, including one described by The Pittsburgh Press in 1895 as "poet-actor William E. Todd."

Todd died in Glendale, California, from a heart attack at the age of 71, survived by his wife, actress Margaret Joslin, and their daughter; his cremated remains are interred at Grand View Memorial Park Cemetery.
