Per Wikipedia:

X-Men, also known as X-Men: The Animated Series, is an animated superhero television series which debuted on October 31, 1992, in the United States on the Fox Kids Network. X-Men was Marvel Comics’ second attempt at an animated X-Men TV series after the pilot, X-Men: Pryde of the X-Men, was not picked up.

This series is very near and dear to my heart.

All 5 seasons are available for streaming, from Archive.org.
