The original Pakenham Post Office opened on 1 February 1859, was renamed Pakenham West on 1 October 1971, and was closed on 15 January 1974. The existing Pakenham Post Office was opened on 11 June 1888 as Pakenham Railway Station Post Office, was renamed Pakenham East in 1908, and further renamed Pakenham on 1 October 1971. The railway station was opened on 8 October 1877 and was a part of the east link connecting Melbourne to Pakenham and other eastern towns.
Pakenham is on the main railway line between Melbourne and Gippsland, and its railway station marks the end of the suburban electrified service. Pakenham Station is the termination point of all services operated by Metro Trains Melbourne heading out of the city, but V/Line trains to and from Gippsland also serve Pakenham.
A second railway station is to be constructed in Pakenham, adjacent to the Lakeside estate. Possible names for the new railway station are Lakeside railway station and Cardinia Road railway station. Selection of either name is unconfirmed and pending a state government decision. Lakeside railway station is also the name given to a railway station on the Puffing Billy heritage railway although it is not on the Melbourne metropolitan commuter railway network.
Pakenham is also on the Princes Highway. The Pakenham bypass allows road traffic between Melbourne and Gippsland to bypass Pakenham, both shortening travel times and alleviating traffic congestion within Pakenham. The main north-south roads through Pakenham take one north to Healesville and south to Koo Wee Rup.

Pakenham is also known for being the birthplace of extreme feeting, an extreme sport in which the athlete performs freestyle stunts by running and jumping of obstacles (Due to similarities between Extreme Feeting and Parkour, there has been much debate over which is the original form of extreme freestyle running). In early 2008 the founders of extreme feeting were involved in a legal battle with WMG over the use of copyrighted songs that appeared in two Extreme Feeting videos without permission.
