Třinec is located about 22 km east of Frýdek-Místek and 30 km southeast of Ostrava. It lies in the historical region of Cieszyn Silesia, on the border with Poland and also near the border with Slovakia, which is about 20 km of the city centre. Třinec lies on the Olza River. The Tyra Stream flows across the municipal territory and joins the Olza in the city centre. The elevation of the built-up area is approximately 300 m above sea level. The northern part of the municipal territory is located in the Moravian-Silesian Foothills. The southern, sparsely populated part is located in the Moravian-Silesian Beskids mountain range, which also lies within the Beskydy Protected Landscape Area. The municipal border runs along the peaks of several mountains, including Ostrý (with an elevation of 1044 m the highest point in Třinec), Smrčina at 1015 m, Šindelná at 1000 m, and Javorový at 1032 m.

Politically, the village then belonged to the Duchy of Teschen, a fee of the Kingdom of Bohemia, which after 1526 became part of the Habsburg monarchy. In 1770, the village had about 200 inhabitants and was completely agricultural. The area was rich in iron ore deposits and had sufficient water energy and a high supply of wood, which were the main reasons to establish an iron works there. The iron mill began operation in 1839, becoming the largest in the entire Cieszyn Silesia, and became a major milestone in the history of the village, which reoriented itself to industry. After the construction of the Košice–Bohumín Railway line in 1871, rapid development of the town took place. After the revolutions of 1848 in the Austrian Empire, a modern municipal division was introduced in the re-established Austrian Silesia. The village as a municipality was added to the political and legal district of Cieszyn. According to censuses conducted in 1880–1910, the population of the municipality grew from 1,792 in 1880 to 3,849 in 1910, with a majority being native Polish speakers (growing from 51.4% in 1880 to 96.6% in 1900 and 96% in 1910), accompanied by a German-speaking minority (at most 32.5% in 1880, then dropping to 12.2% in 1900, and up to 24.3% in 1910) and Czech speakers (peaking in 1890 at 17.4%, then dropping to 6.7% in 1910). In terms of religion, in 1910 the majority were Roman Catholics (63.2%), followed by Protestants (34.5%), and Jews (1.9%). The village was also traditionally inhabited by Cieszyn Vlachs, speaking the Cieszyn Silesian dialect. After World War I, the fall of Austria-Hungary and the division of Cieszyn Silesia in 1920, it became a part of Czechoslovakia. In 1931, Třinec was promoted to a town. Following the Munich Agreement in October 1938, together with the Trans-Olza region, it was annexed by Poland, administratively adjoined to Cieszyn County of the Silesian Voivodeship. It was then annexed by Nazi Germany at the beginning of World War II. After the war, it was restored to Czechoslovakia. In 1946, the municipalities of Lyžbice, Dolní Líštná, and Konská were joined to Třinec. Horní Líštná and Kojkovice were joined in 1959. In 1956–1977, a large housing estate was built in Lyžbice, and it became the most populated town part of Třinec. Afterwards, Lyžbice became a new downtown, taking the place of Staré Město (old town). The municipalities of Guty, Karpentná, Nebory, Oldřichovice, Ropice, Tyra and Vendryně were joined to Třinec in 1980. However, Vendryně became an independent municipality in 1995 and Ropice followed in 2000. In 2018, Třinec became a statutory city.

Třinec is an important cultural centre of the Polish minority in Trans-Olza, which makes up 12.1% of the population (as of 2021).

In 1969, Třinec Iron and Steel Works opened a company museum, which has been jointly operated with the city as the museum of both the company and the city since 1992.
