Neil Stephen Fiala (born August 24, 1956) is an American former Major League Baseball player.

He pinch-hit three times for the St. Louis Cardinals without a hit, then was traded to the Cincinnati Reds on September 10 along with pitcher Joe Edelen for veteran reliever Doug Bair.

In his first appearance for the Reds on September 16, Fiala got his one and only major league hit, a single against Mike Rowland of the San Francisco Giants.

From 2000 until 2002, Fiala served as manager for the River City Rascals of the independent Frontier League.
