Richard B. Connolly
New York City Comptroller
In office 1867–1871

Richard Barrett Connolly (1810 Dunmanway, County Cork, Ireland – May 30, 1880 Marseille, France) was an American politician from New York.

He came to New York City in 1826 and worked first for auctioneers John Haggerty & Sons, and later for merchant Simeon Draper, Haggerty's son-in-law. In 1837, Connolly married Maria S. Townsend (1816–1879), and the two had four children. In 1845, Collector of the Port Cornelius Van Wyck Lawrence appointed Connolly as a clerk in the customs house. In 1849, he became the Bank of North America discount clerk.

As a Tammany Hall Democrat, he was Clerk of New York County from 1853 to 1858; and a member of the New York State Senate (7th D.) from 1860 to 1863, sitting in the 83rd, 84th, 85th and 86th New York State Legislatures. Afterward, he became a discount clerk at the Central National Bank.

He was elected New York City Comptroller in 1867, and became a member of the infamous "Tweed Ring." Some newspaper writers referred to him at that time as "Slippery Dick". He was re-appointed by Mayor A. Oakey Hall as City Comptroller under the "Tweed Charter" and remained in office until his resignation on November 18, 1871. A week later, Connolly was arrested and later indicted on 15 counts of misdemeanors. On New Year's Day, 1872, he was released on bail by Judge George G. Barnard, and went abroad, never to return to the United States.

He died from Bright's disease in Marseille, France, while being a fugitive from justice.
