"Cul de Sac" is a song written by Irish singer-songwriter Van Morrison. It first appeared as the seventh track on Morrison's 1974 album Veedon Fleece, and was released as the B-side to the single "Bulbs".

The song roughly describes traveling on the road, emigration and homecoming.:

"Oh, I traveled far
The nearest star
And Mount Palomar, Palomar, Palomar, Palomar
[…] And when they all,
All go home
Down the cobblestones
You will double back
To a cul de sac"

The lyrics are sparse and added lightly, accenting the melody of the song. "Cul de Sac" is performed in 3/4 time.

"Cul de Sac" was recorded with a separate lineup of musicians than the rest of Veedon Fleece. "Cul de Sac" along with "Bulbs" was recut at Mercury Studios in New York a few months after the main recording for the album took place. It was made with musicians with whom Morrison had never worked before: guitarist John Tropea, bassist Joe Macho and drummer Allen Schwarzberg. It contrasted slightly with the rest of the album as it was given more of a rock music treatment.

"Cul de Sac" was chosen as the B-side to the single “Bulbs”, which was released in 1974 as the lead single for Veedon Fleece. In the UK, it was replaced by “Who Was That Masked Man”.

In his book Van Morrison: Inarticulate Speech of the Heart, John Collis writes:

An alternate version of “Cul de Sac” was released in 2008 on CD.
