Friherre Nils Ericson (born Nils Ericsson; 31 January 1802 – 8 September 1870) was a Swedish mechanical engineer who built canals and railways in Sweden. His younger brother John Ericsson, who emigrated first to England and then the United States, was also an engineer.

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.
