Olga Segler (31 July 1881 – 26 September 1961) was a German woman who died of injuries as a result of crossing the Berlin Wall.
According to the Centre for Contemporary History (ZZF), Segler was both one of the earliest victims of the Berlin Wall and the oldest victim, aged 80-years-old at the time of her death. Additionally, Segler was one of only eight women who was either killed at the Berlin wall, or died as a result of crossing it, among the total of at least 140 victims.
