An Immortal Man (En udødelig mann) is a miniseries on Henrik Ibsen's childhood and youth in three episodes, produced by the NRK in 2006 on the occasion of the 100th anniversary of Ibsen's death. It was directed by Berit Nesheim and written by Siri Senje, and first broadcast on NRK1 on 26, 27 and 28 December 2006.

The series' portrayal of Ibsen's childhood is based on older Ibsen biographies that have been strongly critiqued in newer Ibsen scholarship. Jørgen Haave's book Familien Ibsen [The Ibsen Family] has demonstrated that the portrayal of Ibsen's childhood and parents, as depicted in the miniseries, is misleading and contains numerous inaccuracies. For example the series depicts Knud Ibsen as an alcoholic and the family as poor, both of which are inaccurate.
