Lilla Nyckelviken, 18th-century manor house in Nacka Municipality, Sweden.

Lilla Nyckelviken is an 18th-century manor house in Nacka Municipality featuring a glass veranda and views toward Fjäderholmarna and Blockhusudden across the waters of Lilla Värtan. The building sits by the water with ample windows framing the surrounding landscape.

Lilla Nyckelviken is an 18th-century manor-like building on the shore of Saltsjön in Nacka. Its recorded owners begin with Gustaf Beskow, who held the property from 1836 to 1867, followed by Eduard Carleson until 1876 and Gustaf Rikard Sundström until 1920. The property company Nyckelnäs owned it from 1920 to 1944, Birger Sundström from 1944 to 1956, and Nacka stad from 1956.

The place connects to opera singer Jenny Lind, who spent summer 1865 here and performed from a beach stage while boats gathered to listen. The memory of those special performances remains part of the location's story.

The building is not open to the public; it can only be viewed from the outside. It stands on the shore of Saltsjön inside the Nyckelvikens nature reserve, and the surrounding paths can be walked. Nacka municipality has owned the property since 1956.
