The Louisiana Eagle was a long distance night train operated by the Texas and Pacific Railway that ran from New Orleans to Fort Worth, Texas.

It ran northwest-ward from New Orleans to northwest Louisiana and to the major North Texas cities of Dallas and Fort Worth with continuing service to El Paso on the Missouri Pacific's Texas Eagle, whereas other east-west trains from New Orleans into Texas went to the south, to Houston and San Antonio.

It had a daytime counterpart in the Louisiana Daylight (#27, westbound, 28, eastbound).

[2] The Missouri Pacific ran successor night and day trains to the Louisiana Eagle and the Louisiana Daylight as late as 1968.

[3] By 1969, all that was left was the successor night train, which was shortened to a Marshall, Texas to New Orleans route.
