Mackay is the central suburb and the central business district of the City of Mackay in the Mackay Region, Queensland, Australia. In the 2021 census, the suburb of Mackay had a population of 4,026 people.

Kemmis is a neighbourhood at the southern edge of the suburb (21°09′00″S 149°11′00″E / 21.15°S 149.1833°E / -21.15; 149.1833 (Kemmis)). It was the location of the former Kemmis railway station (21°09′02″S 149°10′44″E / 21.1506°S 149.1788°E / -21.1506; 149.1788 (Kemmis railway station (former))) on the North Coast railway line until the line was diverted to avoid the city centre.

The suburb takes its name from the town, which in turn was named after explorer John Mackay, who led an 1860 expedition into the Pioneer Valley.

The name Kemmis refers to Arthur Kemmis, a member of William Landsborough's 1861 expedition from the Gulf of Carpentaria to Melbourne in search of the Burke and Wills expedition. Kemmis was a partner in the lease of Fort Cooper pastoral run.

Mackay Primary School opened on 12 December 1871. Between 1872 and 1877, it was known as Port Mackay Primary School before becoming Mackay Primary School again. On 28 September 1885, the school was separated into Mackay Boys State School and Mackay Girls and Infants State School. The two schools were amalgamated again on 11 July 1932 to form Mackay Central State School.

The original Mackay station opened in 1885 in Tennyson Street. In 1924, it was relocated to Boddington Street (21°08′56″S 149°10′56″E / 21.1488°S 149.1821°E / -21.1488; 149.1821 (Old Mackay railway station)). In the 1990s, the rail bridge over the Pioneer River needed to be replaced, which presented an opportunity for re-alignment of the railway line to bypass the Mackay CBD. In 1994, the new alignment opened with the new Mackay railway station in the outer suburb of Paget.

St Patrick's College opened on 22 September 1929.

Although Maltese immigrants came to the Mackay area as early as 1883, it was not until in 1944 when Australia's immigration policy was changed to recognise Maltese people as "white British subjects" (and hence acceptable as immigrants under the White Australia policy) that significant numbers of Maltese immigrated to Australia. Many of the Maltese immigrants to Queensland came to Mackay to work in the sugarcane fields and later purchased sugarcane plantations of their own. In 2021, the Mackay Regional Council gave approval for the Maltese community to erect bronze statues of 3 Maltese men sitting on the corner of Victoria and Wood Streets (a popular meeting place for the Maltese community). The statues will be based on a 1994 photo, which is currently in a plaque at the site. The statues are expected to be completed by April 2024.

Mackay Opportunity School opened in 1960. On 29 August 1981, it was renamed Mackay Special School. It closed on 7 May 1997.
