March is shaping up to be an important month for income investors.
With dividend guidance clearer and market volatility still creating pockets of value, this could be a good time to position a portfolio for reliable passive income through the rest of 2026.
Here are three of the best ASX dividend shares to consider this month.

APA Group (ASX: APA)
The first ASX dividend share to look at in March is APA Group.
APA owns and operates energy infrastructure assets across Australia. This includes gas transmission pipelines and renewable energy infrastructure. These are long-life assets that typically operate under contracted or regulated frameworks.
That structure gives APA strong visibility over future cash flows. It is not a business that relies on day-to-day consumer spending or short-term economic swings.
For FY 2026, APA is guiding to a dividend of 58 cents per share. Based on its current share price, this equates to a dividend yield of approximately 6.2%.
For investors seeking above-average yield backed by essential infrastructure assets, APA stands out as a best buy.
Rural Funds Group (ASX: RFF)
Another ASX dividend share that could be among the best to buy this month is Rural Funds Group.
It provides exposure to agricultural assets including cattle properties, almond orchards, vineyards, and cropping farms. Rather than farming directly, it typically leases these assets to experienced operators under long-term arrangements.
This model allows Rural Funds to generate rental-style income while benefiting from exposure to Australian agricultural land and food production.
The company is guiding to dividends of 11.7 cents per share in FY 2026. Based on its current share price, this represents an attractive dividend yield of around 5.5% at current levels.
Agriculture can have cyclical elements, but long-term demand for food production and land scarcity provide structural support for the sector.
Transurban Group (ASX: TCL)
A final ASX dividend share to consider in March is Transurban.
Transurban owns and operates toll roads across Australia and North America, including major urban motorway networks. These are critical transport links with high barriers to entry and long concession lives.
Traffic volumes can fluctuate slightly with economic conditions, but over time, population growth and urban expansion tend to drive higher usage.
For FY 2026, Transurban is guiding to a dividend of 69 cents per share. Based on its current share price, this equates to an attractive dividend yield of approximately 4.75%.
