A thread of the various TV shows where a star of the series sings the Theme Song

The Fall Guy- Starring Lee Majors who Sings The Unknown Stuntman Opener.
Walker Texas Ranger- Starring Theme Vocalist Chuck Norris
Alice- Sung By Lead Actress of the Show Linda Lavin
Eight Is Enough (Third to Last Seasons)- Perdormed by the Show's star Grant Goodeve

I know there are plenty more.

Don't several of the Ninja Turtles voice actors say background lyrics in the original Teenage Mutant Ninja Turtles cartoon theme song?

An easier one to identify is Will Smith singing the them to The Fresh Price of Bel-Air.

David Duchovny, The X-Files

In the original opening of The Drew Carey Show, the title actor covers Moon Over Parma, with Cleveland replacing Eastlake.

Kelsey Grammer sings the closing theme to Frasier.

For Two and a Half Men, it may look like the three main stars (Charlie Sheen, Jon Cryer and Angus T. Jones) were singing the theme, but Chuck Lorre said in an interview that they were just lip-syncing. This was definitely true in the Ashton Kutcher era.

Eva Gabor and Eddie Albert, Green Acres

Jean Stapleton and Carroll O'Connor, All in the Family

Waylon Jennings, The Dukes of Hazzard (he didn't appear onscreen, but he was the narrator)

I think the actors playing the Brady kids in The Brady Bunch sang the theme, but not absolutely sure about that

Family Guy

I think for Disney Channel and Nickelodeon that it is easier to list the shows that this is not the case such as "The Suite Life of Zack and Cody" and its follow-up "The Suite Life on Deck".

Family Guy

This goes for most of MacFarlane's animated empire, including American Dad and The Cleveland Show.

The Monkees

For the first Dukes of Hazzard reunion special, instead of the classic theme song by Waylon Jennings they used a new song performed by the actors who played Bo and Luke.

[vegas1962]

Reba McEntire performed "I'm a Survivor," used as the theme to her sitcom "Reba."

Patti Lupone and the cast sang "Ob-La-Di, Ob-La-Da" for the theme to the ABC sitcom "Life Goes On."

Nell Carter did the theme to her sitcom "Gimme a Break."

There's a list of these over at TV Tropes.

Not for the first season or two.

I think for Disney Channel and Nickelodeon that it is easier to list the shows that this is not the case such as "The Suite Life of Zack and Cody" and its follow-up "The Suite Life on Deck".

True. However, "Shake It Up!" had Selena Gomez performing the theme, and she wasn't on the show, and "Andi Mack," had Sabrina Carpenter performing the theme song, but she wasn't on that show either.
