James Smart (22 March 1804 – 27 May 1870) was a British police officer who served as head of the City of Glasgow Police from 1848 until his death in 1870, first as chief superintendent before being designated as Glasgow's first chief constable in 1862.

Smart served as superintendent of the Burgh of Calton from 1835 until its amalgamation into Glasgow in 1846 and as assistant superintendent of Glasgow's Eastern Division Glasgow from 1846 to 1848 in which he was praised for his handling of the Glasgow bread riots of 1848.

Smart was born on 22 March 1804 in Cathcart, Glasgow. He worked in England as a traveller selling tea until his employer went out of business. Smith then joined the Metropolitan Police and served between December 1830 and March 1831. Smith resigned his position and returned to Glasgow to take up employment with his old boss, who again became bankrupt within half a year of him working in the police. He became a patrolman in the Burgh of Gorbals Police in October 1831, before being promoted to sergeant in August 1832 and then lieutenant. He resigned from Burgh of Gorbals Police in June 1835 after being appointed superintendent of the Burgh of Calton. In December 1839, Smart unsuccessfully applied to serve as Superintendent of the City of Dundee Police. He retained his position as head of Calton's police force following its amalgamation into the city of Glasgow, along with Gorbals and Anderston in 1846 as assistant superintendent of Glasgow's Eastern Division.

On 6 March 1848, bread riots occurred in Glasgow leading to warehouse windows being smashed and firearms and other weapons being stolen from gun-smiths. The Glasgow Herald described the city as being in a "state of utmost apparent security" and the following day Smart, escorted by a group of pensioners armed with firearms approached the mob. The mob reportedly began to "hoot and groan" and throw stones at Smart and the pensioners. The pensioners were then ordered by Smart to charge at the mob to disperse them but they possibly misunderstood the orders and fired at the crowd instead. The riot led to three people receiving fatal wounds and four people being injured. The Glasgow Herald reported that it was soon acknowledged that Smart's "firmness had prevented the riot attaining even more formidable proportions" with Sheriff Sir Archibald Alison stating that "his conduct was not only unexceptionable but highly meritorious in the trying circumstances".

The bread riots led to the resignation of Glasgow's Chief Superintendent William Pearce who had received complaints over the way in which he dealt with the crowds. He was succeeded by Assistant Superintendent Cameron for an interim period of 14 days before he was succeeded by Henry Miller. Miller who had previously served as Glasgow's Chief Superintendent between 1836 and 1844, took nine weeks' sick-leave after his health deteriorated before he resigned on 4 December 1848. Smart was appointed to the vacant position on 18 December 1848.

In 1849, Queen Victoria, Prince Albert and the Prince of Wales visited Glasgow on route to Balmoral Castle. It was the city's first royal visit since James VI and I visited the city in 1617 with an estimated 400,000 people cheering along the route which was well marshalled by the city's police force.

On 28 August 1850, Smart discontinued the practice of night constables calling the hours and half hours with the exception of five and half past five. On 26 May 1856, he ordered that superior officers in the force no longer arrange excise commissions so that they could focus their attentions on the prevention of illicit distillation. Smart requested that the Scottish Office produce criminal statistics from 1857 which he used to make "repeated representations to his Police Board bemoaning the carelessness of the public affecting his crime figures". The Glasgow Police Act 1862 (25 & 26 Vict. c. cciv) designated Smart as Glasgow's first Chief Constable; previously only county police officers could use the title.

Smart did not support the lighting of stairs being the legal responsibility of home owners as many did so by breaking the law and so in 1864, after unsuccessfully trying to convince local authority representatives that they should carry out the task, he flooded the police courts with 17,472 cases to prove how impractical the existing system was. Following this the board would take on the responsibility of lighting the people of Glasgow's stairs. Smart also ensured that allegations against the police were thoroughly investigated such as in 1865 when a complaint was made when a group of young boys were detained for allegedly purposefully damaging a butcher's van.
