Navan Junction was a railway station serving the town of Navan in County Meath. As the name suggests, the station was located at the junction of two railway lines. The first was a branch line off the main line between Belfast and Dublin, which connected Drogheda and Oldcastle, and opened in 1850. The second, which opened in 1862, was also a branch line, this time off the line from Dublin to Sligo, connecting Clonsilla and Navan. This line was later extended as far as Kingscourt in 1865.
