George L. Wellington (January 28, 1852 - March 20, 1927) was a Republican member of the United States Senate, representing the State of Maryland from 1897-1903. He also represented the sixth district of Maryland in the U.S. House of Representatives.
Wellington was born in Cumberland, Maryland and attended a German school with some private instruction. He went on to be a clerk in the Second National Bank of Cumberland in 1870 and later was a teller.
From 1882-1888 and 1890, Wellington was treasurer of Allegany County, Maryland. He unsuccessfully ran for Comptroller of Maryland in 1889, but was chosen as the assistant treasurer of the United States at Baltimore, Maryland from 1890-1893.
Wellington was unsuccessful in his campaign to be elected to the 53rd Congress in 1892, but two years later, in 1894, was elected as a Republican to the 54th Congress. After serving one term, he was elected to the United States Senate in 1896, serving one term from 1897-1903, choosing not to run for re-election in 1902. As senator, he was chairman of the U.S. Senate Committee to Establish a University of the United States (55th and 56th Congresses).
In 1913, Wellington again sought election as senator, but as a member of the Progressive Party. He was not elected and, following the election, he engaged in civic activities. He became president of two banks and held an interest in the electric railways and electric companies in his hometown of Cumberland.
Wellington died in Cumberland, and is buried at Rose Hill Cemetery.
