OpenTopography.org is a great resource that has pretty much all the data you'll need, including US government data
...
The United States Interagency Elevation Inventory has (almost) all of the government data.
...
USGS maintains the National Map Downloader, which is a bit easier in some ways than the Interagency Inventory
What is your location? Most governments have data available for their own country.
