Thomas H. Ogden (born 1946) is an American psychoanalyst and writer who practises, teaches and supervises in San Francisco. He trained in psychiatry at Yale and spent a year at the Tavistock Clinic in London. Over four decades he has built a body of work that reads the British object-relations analysts closely, among them Melanie Klein, Donald Winnicott and above all Wilfred Bion, and turns their ideas toward the lived experience of the analytic hour.
His early work recast projective identification as an interpersonal process with distinct phases. It also read Klein's positions not as stages of development but as coexisting modes of generating experience, to which he added a more primitive autistic-contiguous position. In the 1990s he described the analytic third, a subjectivity that analyst and patient create together, and made the analyst's reverie a principal way of reaching it. From the early 2000s, building on Bion's theory of dreaming, he came to see analysis as helping the patient dream experience that had gone undreamt, and so come more fully into being. In his later writing he calls this turn ontological psychoanalysis.
Alongside his clinical theory he has written at length on reading and writing, on poetry and on the relation between psychoanalysis and literature. He has also published three novels.
