Lajkovac (Serbian Cyrillic: Лајковац) is a town and municipality located in the Kolubara District of western Serbia.

In 1914, Dual Monarchy army stormed the city and destroyed much of the infrastructure; shortly afterwards, however the same force continued construction of a line to Čačak.

After the end of the war in 1921, Čačak line was completed, connecting Lajkovac with Sarajevo and the Adriatic seaports of Dubrovnik and Herceg Novi.

The town prospered greatly becoming a major railway crossroads and this period is today considered as the Lajkovac's "Golden Age".

Much of the narrow-gauge infrastructure remains in the town today, such as a water tower (nicknamed Buzometar), turntable, roundhouse and many rolling stock sheds.
