Nanna Kristensen-Randers née Berg (1864–1908) was a Danish lawyer and folk high school administrator.

When the family settled in Copenhagen in 1884, she attended N. Zahle's School where she was said to have been extraordinarily hard-working and gifted.

In 1887, she successfully completed the course introduced under the political reforms to solve the problem of inadequate manning of the lower courts of law.

This state of affairs continued until 1909 when Henny Magnussen was permitted to follow the full university law course leading to the degree cand.jur.

She became an active member of the Danish Women's Society, lecturing at various folk high schools and colleges, including the one at Ollerup.
