Update

As described in the newer answer below, the modern solution is to run:

ip addr show

The MAC address is shown in the link/ether field.

Original Answer

Open a terminal and run ifconfig:

ifconfig | grep HWaddr

by the way, do you know what the "if" of "ifconfig" stands for? – The Student Jul 16 '10 at 15:58

ifconfig is short for "Interface Configurator" – Brian Kintz Jul 16 '10 at 16:10

Use ip command instead of the outdated ifconfig

Command :

$ ip addr show

link/ether field of the output is the MAC address (Both for Wi-fi and ethernet connections, MAC address is represented by link/ether). Mostly this will be present in the second line.

Example :

$ ip addr show
1: enp2s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000
    link/ether a0:54:9f:53:b2:6e brd ff:ff:ff:ff:ff:ff

In my case a0:54:9f:53:b2:6e is the MAC address.

By the way, just `ip a` works too, but the longer syntax is more clear. – Nagev Oct 22 '18 at 10:05

On Ubuntu 20.04.02 LTS, there is no HWaddr in the output from ifconfig. Instead, look at ether:

$ ifconfig | grep ether

Try ifconfig, and look at the "HWaddr".

okay, this is a very easy solution. 1/ Open a terminal 2/ ifconfig A list of network capable devices will be displayed. If you are using wireless, it usually is called wlan0, but can also be named pan0 wifi0 etc. A physical conection is most likely eth0. on the first line you will see your mac address. here is a sample of what you might see eth0 Link encap:Ethernet HWaddr 00:00:00:00:00:00

that's it.

You can spoof your mac address too with macchanger (sudo aptitude install macchanger) just type man macchanger to learn more

You can also right-click on the GNOME Network Manager. There you choose connection information and the following window shows you the hardware address. See also NetworkManager at Ubuntus Wiki.
