Friherre Nils Ericson (31 January 1802 – 8 September 1870) was a Swedish mechanical engineer (as was his younger brother John Ericsson, who emigrated to England and then the USA).
He became a prominent Swedish canal and railway builder.

Born Nils Ericsson, he was raised to the untitled nobility by king Oscar I of Sweden in 1854, and with this he reverted to a spelling of his surname with only one "s".
In 1859 he was made a Friherre (equivalent to English Baron), the 403rd such elevation to Sweden's titled nobility.
