The National New York Central Railroad Museum (reporting mark NNYX) is a railroad museum located in Elkhart, Indiana dedicated to the preservation of the New York Central Railroad (NYC).

The museum includes several outdoor equipment displays, indoor model railroads, artifacts from the NYC and other railroad related exhibits including educational displays pertaining to the history of railroading. The museum is currently expanding its dedication to the preservation of both local and national railroad heritage. The museum consists of a modified NYC 20th Century Limited train set and freight house built by the Lake Shore & Michigan Southern Railway (LS&MS) in 1907.

Elkhart was a vital link between East and West during the growth of railroading in the U.S. In 1833 the LS&MS built a line through town; it was later acquired by the NYC in 1914.

The museum is situated opposite the Norfolk Southern Railway (NS) east–west main line; NS freight trains pass approximately every 15 minutes. Amtrak's Elkhart Station is also within walking distance; daily service is provided by the Lake Shore Limited (Chicago-Boston/New York) and Capitol Limited (Chicago-Washington, D.C.).

The bulk of the museum's collection & the museum site was originally owned by the Lakeshore Railroad Historical Foundation (LRHF), A non-profit rail preservation group based in Elkhart. The group subs-subsequently donated their collection & sold the property to the city in early 1987. In 1987, the museum was opened.
