John D. Naylor (August 10, 1893 – February 8, 1955) was an American athlete and college sports coach.

Before his coaching career, Naylor was a baseball, basketball, and football player in several low-level minor leagues.

[2] Following his time at Delaware University, Naylor became a baseball player in several low-level minor leagues.

An article in The Evening Journal wrote, "Four days remain until the opening of the new Atlantic League, and judging by the all round work of Johnny Naylor, a New Castle lad, who is working out with the Allentown Club, he is going to hold down a regular berth ... During his stay in Allentown the past five days, Naylor has been playing shortstop.

[7] Every Evening reported, "Baseball suffered another loss yesterday when John D. Naylor, one of the most popular devotees of the good old game, left for Wissahickon Barracks, Cape May, N. J. Naylor enlisted several weeks ago as a musician in the Naval Coast Reserve and received his call to the colors on Wednesday of last week.

[13] In November 1921, Naylor was hired as one of two assistant coaches for the 1921–22 New Castle High School basketball season.

[16] By October 1925, Naylor's soccer team was undefeated against other schools, including some considered to be best in the area.

[16] John J. Brady of The Morning News wrote, "Everyone who follows athletics in this city is aware of the ability of Johnny Naylor as a ball player, as a court star, and as a successful coach in both of these lines, but few realized that he also was well versed on the dribbling game.

"[16] The Morning News also wrote, "The success of Beacom's is measured in a single word, "teamplay."

Every member of the squad has faith in the ability of coach Naylor and they pull for a team victory.

Individual play had little room on Beacom teams ... Johnny Naylor and his squad deserve all the praise that is being heaped upon them.

By the beginning of his thirteenth coaching season, Naylor had won more than 75 percent of all combined basketball, football, soccer, tennis, and baseball games.
