You'll want to use getnewaddress. Here is the output of bitcoin-cli help getnewaddress from Satoshi:0.17.0.1: 

bitcoin-cli getnewaddress( "label" "address_type" )

Returns a new Bitcoin address for receiving payments.
If 'label' is specified, it is added to the address book 
so payments received with the address will be associated with 'label'.

Arguments:
1. "label"          (string, optional) The label name for the address to be linked to. If not provided, the default label "" is used. It can also be set to the empty string "" to represent the default label. The label does not need to exist, it will be created if there is no label by the given name.
2. "address_type"   (string, optional) The address type to use. Options are "legacy", "p2sh-segwit", and "bech32". Default is set by -addresstype.

Result:
"address"    (string) The new bitcoin address

Examples:
