The Delta N or Thor-Delta N was an American expendable launch system used for nine orbital launches between 1968 and 1972. It was a member of the Delta family of rockets, and the last Delta to be given an alphabetical designation - subsequent rockets were designated using a four digit numerical code.

The Delta N consisted of two stages. The first stage was the Long Tank Thor, a stretched version of the Thor missile, previously flown on the Delta L and Delta M. Three Castor-2 solid rocket boosters were attached to increase thrust at lift-off. A Delta E was used as the second stage. If an increased payload capacity was required, six boosters were flown instead of three, in a configuration known as the Delta N6, or "Super Six". Three launches used the N6 configuration.

Delta N rockets were launched from Launch Complex 17A at the Cape Canaveral Air Force Station, and SLC-2 at Vandenberg AFB. One of the launches, a Delta N6 with ITOS B, failed. The satellite was placed into an incorrect and unusable orbit.
