With the caveat that there really is no such thing (every dataset will require case specific reduction; standard processing and reduction are inadequate in all but the simplest of cases), here is a brief list:

  1. The 2 Megasecond Chandra observations of the Southern Deep Field, which have been processed, reduced, and mosaiced. (Coincidentally, just last week Peter Freeman had asked me for a nice dataset on which to try out spatial analysis algorithms, and for which some analysis already existed for people to check their results against. These were the data I recommended.)
  2. HEASARC’s W3Browse gives direct access to archived data from various missions. The data products have been already processed in some standard way.
  3. The Penn State Center for Astrostatistics maintains training datasets of various types
  4. ADC, as pointed out by Brian

There are many more, I am sure, and if people find any particularly good ones, please point them out in the comments!
