Main Website (“Kids” Side):
The most complete archive I've found is sourced from http://www.nostalgiakidssites.com/nickjr.html
Unfortunately due to this being a random person's site, I can’t guarantee this website will be around forever, but it does work as of 3/8/2026. This website works SIGNIFICANTLY better then the WayBack Machine Nick Jr site. Most links within this archives work, but not every single one, so beware! (If the main website goes down there IS a WayBack Machine archive of this site as well: https://web.archive.org/web/20260000000000*/http://www.nostalgiakidssites.com/nickjr.html)
Main Website (“Grown-Ups” Side):
Most of the stable “Grown-Ups” links are from 2004 and after, but I will still link the oldest “working” archive.
Oldest “Working” Archives (Many links won't lead to the correct page, but rather a prompt telling you to download flash and/or shockwave): 1998 (Not explicitly labeled “Grown-Up”), 2000
During (at least) 1998 to early 2001, Nickelodeon ran a website called http://www.teachers.nick.com (now defunct). This website houses many resources for teachers based on the times current Nick Jr programing. The website later became embedded into the “Grown-Ups” sections of the Nick Jr website.
