Colonel James Hughes CB (died 26 November 1845) was a British Army officer and politician.
In 1803, then a captain in the 48th Foot, Hughes exchanged into the 18th Light Dragoons, the regiment in which he was to remain for the rest of his career.
He purchased a majority in 1812, was appointed Companion of the Order of the Bath (CB) in 1815, and promoted brevet lieutenant-colonel in 1817 and colonel in 1837, the latter while on half-pay.
He unsuccessfully contested Grantham in 1818, being returned fourth in the poll with 14 votes of 1376 cast.
He was again returned from Grantham in 1831, but the Tollemache interest regained the seat in 1832.
