Regina—Lumsden—Lake Centre (formerly known as Regina—Arm River) was a federal electoral district in Saskatchewan, Canada, that was represented in the House of Commons of Canada from 1997 to 2015.

The district included the northwestern part of the city of Regina and extended outward from Regina to Nokomis in the north, Davidson in the northwest and Tugaske in the west.

The electoral district was created as "Regina—Arm River" in 1996 from Regina—Lumsden and portions of Moose Jaw—Lake Centre, Mackenzie and Regina—Qu'Appelle ridings.

In 1997, its name was changed to "Regina—Lumsden—Lake Centre".

The riding was dissolved in the 2012 Canadian federal electoral redistribution, redistributed between Regina—Lewvan, Regina—Qu'Appelle, and Moose Jaw—Lake Centre—Lanigan.
