We study N = 1, 2, 4 higher spin superalgebras in four dimensions and higher spin gauge theories based on them. We extend the existing minimal N = 2, 4 theories and find a minimal N = 1 theory. Utilizing the basic structure of the minimal N = 8 theory, we express the full field equations for the N = 1, 2, 4 theories in a universal form without introducing Kleinian operators. We also use a non-minimal N = 4 higher spin algebra tensored with U (3) to describe a higher spin extension of N = 4 supergravity coupled to the massless vector multiplets arising in the KK spectrum of 11D supergravity on the N = 3 supersymmetric AdS4 × N010 background. The higher spin theory also contains a triplet of vector multiplets which may play a role in the super-Higgs effect in which N = 4 is broken down to N = 3.
