Sigismund von Lindenau (c. 1484 – 4 January 1544)[1] was Bishop of Merseburg from 1535 to 1544.

He was the last Catholic bishop of the Merseburg diocese until Michael Helding was appointed in 1549.

Just one year after Sigismund's death, Martin Luther preached in Merseburg Cathedral.

Sigismund carried out structural measures at Lützen Castle.

In the castle of Bad Lauchstädt, his coat of arms bears witness to his building activity.
